四川省退耕还林统计数据2001退耕还林(草)核查面积按坡度和树种统计表_附表

本数据记录了四川省退耕还林统计数据中2001退耕还林(草)核查面积按坡度和树种统计表_附表的统计单位、代码、树种、上报面积、核实面积、合格面积总计、合格面积15°以下、合格面积15°至25°、合格面积25°以上、待补植面积总计、待补植面积15°以下、待补植面积15°至25°、待补植面积25°以上、失败面积总计、失败面积15°以下、失败面积15°至25°、失败面积25°以上、损失面积总计、损失面积15°以下、损失面积15°至25°、损失面积25°以上等记录。退耕还林数据在林业科学研究和森林资源管理中十分重要的数据，包括不同退耕还林森林类型的空间分布状况、面积大小，行政区划及区划代码等信息。目前的退耕还林数据很多是由二类调查资料数据获得的，是在林业生产中十分重要的图面资料，对退耕还林管理部门决策提供科学依据。

This dataset contains the following records from the attached table of the 2001 cropland conversion to forest and grassland verification area statistics grouped by slope gradient and tree species within the Sichuan Province cropland conversion statistical dataset: statistical units, codes, tree species, reported area, verified area, total qualified area, qualified area under 15° slope, qualified area between 15° and 25° slope, qualified area above 25° slope, total area requiring replanting, area requiring replanting under 15° slope, area requiring replanting between 15° and 25° slope, area requiring replanting above 25° slope, total failed area, failed area under 15° slope, failed area between 15° and 25° slope, failed area above 25° slope, total lost area, lost area under 15° slope, lost area between 15° and 25° slope, and lost area above 25° slope. Cropland conversion data is of paramount importance to forestry scientific research and forest resource management, as it includes information such as the spatial distribution patterns, area sizes, administrative divisions and their corresponding codes of different cropland conversion forest types. Most current cropland conversion datasets are derived from detailed forest inventory data, which serves as crucial graphic materials for forestry production and provides scientific foundations for decision-making by cropland conversion management departments.
