江苏下蜀城市森林生态系统定位研究

长江三角洲城市森林生态系统定位研究站（原名“江苏下蜀城市森林生态系统定位研究站”，简称下蜀站）是国家林业局15个森林生态系统定位研究网站之一。1986年正式建站，在江苏省句容县境内，位于长江下游宁镇山脉东段丘陵区。人工林主要为松、杉、竹林，以栓皮栎、麻栎和其它阔叶树种组成的天然次生阔叶林是本地区最有代表性的森林植物群落，由于下蜀站临近城市，1996年改名为下蜀城市森林生态系统定位研究站。2005年底，为适应城市生态研究的需要，改名为“长江三角洲城市森林生态系统定位研究站”。建站后得到国家林业局的长期资助，还得到国家自然科学基金会批准的5个项目的资助以及江苏省教育厅和南京林业大学的资助。 建站20多年来，在栎类次生林、杉木林、火炬松林和毛竹林设立定位观测点，建气象观测站5个，气象观测铁塔1座、径流场6个、固定样地15个、测定生物多样性和森林演替样带一条，另在紫金山、安徽琅琊山等地设立临时观测点。 根据国家林业局的统一部署和所处的自然和社会经济特点，本站研究内容以基础理论研究为主，主要包括以下6个方面：1、城市森林生态系统的研究 2、次生栎林、杉木林和火炬松林生长规律和生产力的研究 3、城市绿化树种生理生态特性的研究 4、森林生物多样性和森林演替的研究 5、森林生态功能的研究（1）森林小气候研究和树冠遮阴的动态研究 （2）森林水循环的研究 （3）森林营养元素循环的研究。

The Yangtze River Delta Urban Forest Ecosystem Research Station (formerly named "Jiangsu Xiashu Urban Forest Ecosystem Research Station", abbreviated as Xiashu Station) is one of the 15 forest ecosystem fixed-point research stations under the State Forestry Administration. Established in 1986, it is located in Jurong County, Jiangsu Province, in the hilly area of the eastern section of the Ningzhen Mountains in the lower reaches of the Yangtze River. The main planted forests here are pine, fir and bamboo forests, while the natural secondary broad-leaved forests dominated by Quercus variabilis, Quercus acutissima and other broad-leaved tree species are the most representative forest plant communities in this region. As Xiashu Station is close to urban areas, it was renamed "Xiashu Urban Forest Ecosystem Research Station" in 1996. By the end of 2005, it was renamed "Yangtze River Delta Urban Forest Ecosystem Research Station" to meet the needs of urban ecological research.

Since its establishment, the station has received long-term funding from the State Forestry Administration, as well as funding for 5 projects approved by the National Natural Science Foundation of China, plus support from the Jiangsu Provincial Department of Education and Nanjing Forestry University.

Over the past 20+ years since its foundation, the station has set up fixed observation points in oak secondary forests, Chinese fir forests, slash pine forests and moso bamboo forests, built 5 meteorological observation stations, 1 meteorological observation tower, 6 runoff plots, 15 permanent sample plots, 1 transect for biodiversity and forest succession surveys, and established temporary observation sites in locations such as Zijin Mountain and Langya Mountain in Anhui Province.

Based on the unified deployment of the State Forestry Administration and its local natural and socio-economic characteristics, the station's research focuses on basic theoretical studies, covering the following 6 aspects:
1. Research on urban forest ecosystems
2. Research on growth patterns and productivity of secondary oak, Chinese fir and slash pine forests
3. Research on physiological and ecological characteristics of urban greening tree species
4. Research on forest biodiversity and forest succession
5. Research on forest ecological functions:
(1) Research on forest microclimate and dynamic changes of canopy shading
(2) Research on forest water cycle
(3) Research on forest nutrient cycling
