中国北方地区森林、草原变迁和生态灾害的历史研究

中国北方地区在过去的历史时期曾经有广泛分布的森林和草原，生态环境良好。 　　从新石器时代的仰韶文化开始，为了获取猎物、建造居住场所、种植农作物，原始人群已经开始使用火、石刀、石斧、石犁进行劳动，一些原始部落居住地周围的森林、草原开始受到最初的破坏。 　　进入奴隶社会，各个原始部落之间战争频繁发生，烧毁消耗一些林木，冶炼、制陶、建筑等手工业不断发展，开始砍伐大片森林，农业的兴起又使大片次生林、灌丛、草地受到开垦，成为农田。今河北省、山西省南部、山西省中部所属地区的森林、草原受到了较大规模的破坏。 　　战国时期，进入封建社会，农业获得了进一步发展，陶瓷、冶炼、制盐、建筑等手工业快速发展，同时，各个诸侯国兴修水利工程，修筑高大坚固的防御设施，建造规模庞大的宫殿、庙宇以及不断发生的征战，都使平原地区大面积森林受到破坏。战国后期华北平原的森林已经基本消失。 　　秦、汉时期，是中国历史上封建社会的第一个高峰，社会生产力有了很大发展，农业生产工具和生产技术出现了创新局面。今河北省、北京市、山西省南部、陕西省中部、甘肃省东部所属的平原和丘陵地区森林全部消失，绝大部分已经开垦成为农田。由于修建万里长城，鄂尔多斯高原和阴山山脉的森林受到大量砍伐。 　　由于地表植被受到严重破坏，黄土高原地区开始出现严重的水土流失问题。黄河水灾日益严重。同时，开始了在西北森林草原、草原以及荒漠草原地区大规模的屯垦。上述地区大面积森林、草原受到破坏，农业人口不断增加，农耕区域不断扩大。 　　唐、宋时期，黄土高原上已经开辟出广阔的农业区，西北地区积极推行屯垦，河西走廊、河套地区、陕西北部地区的森林、草原再一次遭受严重破坏。陕西秦岭、子午岭、宁夏罗山、贺兰山、六盘山、甘肃洮河、陇南山地森林先后遭受破坏，太行山、吕梁山的森林开始受到大规模砍伐。 　　元代至民国，华北地区的山区森林遭受了严重破坏，大青山、贺兰山、鄂尔多斯高原、燕山、太行山、吕梁山等等山区的森林都已经受到彻底破坏。黄土高原的祁连山、六盘山、陇东森林草原地区已经变成了荒山秃岭。秦岭森林破坏严重，黄土高原的关山、黄龙山、桥山原始森林已经消失。 　　清朝政府实行“移民实边”、“借地养民”的政策，大量放垦内蒙古草原，造成长城沿线以及河西走廊地区大面积草原被开垦。 　　清朝末年至民国时期，沙皇俄国和日本侵略者掠夺了中国东北以及西北地区大量森林资源。 　　中华人民共和国成立到20世纪末，平原地区和干旱地带造林、封山育林取得很大成绩。但是全国主要林区超量采伐，消耗量大于生长量，出现了森林资源危机。草原地区由于超载过牧，导致大部分草场退化，同时，草原开荒种粮造成大面积草原消失。 　　森林、草原大量破坏导致了严重的生态灾害。从西汉时期开始，黄土高原地区出现了严重的水土流失，黄河流域水灾频繁发生，危害程度越来越大。随后，永定河、汾河等河流也出现了严重水灾。同时中国北方地区的旱灾也呈现出不断增加的趋势。主要河流水文状况恶化，大量湖泊、湿地消失，野生动植物资源急剧减少。 　　农牧交错地区、绿洲周围草原的沙漠化面积不断发展。草原地区的沙漠化主要包括乌兰布和沙漠、毛乌素沙地、科尔沁沙地、呼伦贝尔沙地，由于大强度的农业开垦和频繁的战乱，从东汉开始，这些地区逐渐产生了严重的沙漠化。 　　荒漠地区的沙漠化主要是指塔克拉玛干沙漠、河西走廊沙漠、腾格里沙漠、古尔班通古特沙漠、柴达木盆地沙漠、巴丹吉林沙漠、库姆塔格沙漠周围的荒漠草原，历史时期，荒漠地带的沙漠化进程也在不断扩展。 　　沙尘天气不断增加，严重影响了中国北方地区人民的日常生活，强烈制约着本地区经济和社会的发展。 　　在引起森林、草原巨大变迁的因素当中，人为因素是起主导作用的，自然因素也起到了一定作用。在导致中国森林、草原减少的人为因素当中，人口的不断增加而造成的对森林、草原资源的持续压力是根本的原因。 　　中国北方地区森林、草原长期受到破坏的原因是落后的生产方式和落后的科学技术，今天，在中国共产党的领导下，中国的科学技术和国民经济已经取得了长足发展，中国政府已经把“保护和恢复生态环境”作为一项基本国策，长期不懈，坚决贯彻执行“退耕还林”“退耕还草”“退牧还草”政策是改变中国北方地区生态环境，建设和谐社会的重要保证。 　　在中国北方地区保护和修复环境的生态建设中，必须根据不同区域的土壤水分条件，注意林业、草业、农业协调发展，实事求是，遵循生态学和经济学规律，采取“宜林则林”，“宜草则草”，“宜农则农”的科学措施。

During historical periods, the North China region was widely covered with forests and grasslands, boasting a favorable ecological environment.
Starting from the Yangshao Culture of the Neolithic Age, primitive human groups began to use fire, stone knives, stone axes and stone plows for labor in order to obtain prey, build dwellings and grow crops. As a result, forests and grasslands around the settlements of some primitive tribes began to suffer initial damage.
Entering the slave society, frequent wars broke out between primitive tribes, burning and consuming some forests. With the continuous development of handicraft industries such as smelting, pottery making and construction, large-scale deforestation began. The rise of agriculture also led to the reclamation of large areas of secondary forests, shrubs and grasslands into farmland. The forests and grasslands in present-day southern Hebei Province, southern and central Shanxi Province suffered relatively large-scale damage.
During the Warring States Period, China entered feudal society. Agriculture developed further, and handicraft industries such as ceramics, smelting, salt making and construction grew rapidly. Meanwhile, various vassal states built water conservancy projects, erected tall and solid defensive facilities, constructed large-scale palaces and temples, and carried out continuous wars, all of which caused large-scale damage to forests in the plain areas. By the late Warring States Period, forests on the North China Plain had basically disappeared.
The Qin and Han dynasties marked the first peak of feudal society in Chinese history. Social productivity greatly developed, and innovations emerged in agricultural production tools and technologies. The forests in the plain and hilly areas of present-day Hebei Province, Beijing, southern Shanxi Province, central Shaanxi Province and eastern Gansu Province had all disappeared, most of which had been reclaimed into farmland. Due to the construction of the Great Wall, large numbers of forests in the Ordos Plateau and Yinshan Mountains were felled.
As surface vegetation was severely damaged, serious soil erosion began to occur in the Loess Plateau. Floods in the Yellow River became increasingly severe. Meanwhile, large-scale state-sponsored farming was launched in the forest-steppe, steppe and desert steppe areas of Northwest China. Large areas of forests and grasslands in these regions were damaged, the agricultural population continued to grow, and farming areas continued to expand.
During the Tang and Song dynasties, vast agricultural areas had been reclaimed on the Loess Plateau. The Northwest China region actively carried out state-sponsored farming, and the forests and grasslands in the Hexi Corridor, Hetao Area and northern Shaanxi Province suffered severe damage again. Forests in the Qinling Mountains, Ziwuling Mountains (Shaanxi), Luoshan Mountains (Ningxia), Helan Mountains, Liupan Mountains, Taohe River Basin (Gansu) and Longnan Mountainous Area were damaged one after another, while forests in the Taihang Mountains and Lüliang Mountains began to be felled on a large scale.
From the Yuan Dynasty to the Republic of China period, mountain forests in North China suffered severe damage. Forests in the Daqing Mountains, Helan Mountains, Ordos Plateau, Yanshan Mountains, Taihang Mountains, Lüliang Mountains and other mountainous areas had been completely destroyed. The forest-steppe areas of the Qilian Mountains, Liupan Mountains and eastern Gansu on the Loess Plateau had turned into barren hills. Forests in the Qinling Mountains were severely damaged, and the primeval forests in the Guanshan Mountains, Huanglong Mountains and Qiaoshan Mountains on the Loess Plateau had disappeared.
The Qing government implemented the policies of "resettling people to strengthen border areas" and "borrowing land to support the people", and opened up large areas of Inner Mongolia grasslands for reclamation, resulting in the reclamation of large swathes of grasslands along the Great Wall and in the Hexi Corridor.
From the late Qing Dynasty to the Republic of China period, Tsarist Russia and Japanese invaders plundered a large amount of forest resources in Northeast and Northwest China.
From the founding of the People's Republic of China to the end of the 20th century, great achievements were made in afforestation and enclosure for forest restoration in plain areas and arid zones. However, over-logging occurred in major forest regions across the country, with consumption exceeding growth, leading to a forest resource crisis. In grassland areas, overgrazing caused degradation of most pastures, while reclamation of grasslands for grain cultivation resulted in the disappearance of large areas of grasslands.
Massive destruction of forests and grasslands led to severe ecological disasters. Starting from the Western Han Dynasty, serious soil erosion occurred in the Loess Plateau, and floods in the Yellow River basin occurred frequently with increasing severity. Subsequently, major rivers such as the Yongding River and Fen River also suffered severe floods. Meanwhile, droughts in North China showed a growing trend. Hydrological conditions of major rivers deteriorated, large numbers of lakes and wetlands disappeared, and wildlife resources declined sharply.
The area of desertification in agro-pastoral ecotones and oasis-surrounding grasslands continued to expand. Desertification in grassland areas mainly covers the Ulan Buh Desert, Mu Us Sandy Land, Horqin Sandy Land and Hulunbuir Sandy Land. Due to intensive agricultural reclamation and frequent wars, severe desertification gradually emerged in these regions starting from the Eastern Han Dynasty.
Desertification in desert areas mainly refers to the desert steppes surrounding the Taklamakan Desert, Hexi Corridor Desert, Tengger Desert, Gurbantunggut Desert, Qaidam Basin Desert, Badain Jaran Desert and Kumtag Desert. During historical periods, the desertification process in desert zones also continued to expand.
Sand and dust weather increased continuously, seriously affecting the daily lives of people in North China and strongly restricting the economic and social development of the region.
Among the factors that caused tremendous changes in forests and grasslands, human activities played a dominant role, while natural factors also played a certain role. Among the human factors that led to the reduction of forests and grasslands in China, the continuous pressure on forest and grassland resources caused by growing population was the fundamental cause.
The long-term damage to forests and grasslands in North China was caused by backward production modes and backward science and technology. Today, under the leadership of the Communist Party of China, China's science and technology and national economy have achieved considerable development. The Chinese government has taken "protecting and restoring the ecological environment" as a basic national policy. Persistently and resolutely implementing the policies of "Grain for Green Project", "Returning Farmland to Grassland" and "Returning Grazing Land to Grassland" is an important guarantee for improving the ecological environment of North China and building a harmonious society.
In the ecological construction of environmental protection and restoration in North China, it is necessary to consider the soil moisture conditions of different regions, pay attention to the coordinated development of forestry, grassland industry and agriculture, proceed from reality, follow the laws of ecology and economics, and adopt scientific measures of "afforest where suitable for forests", "grow grass where suitable for grass" and "develop agriculture where suitable for agriculture".
