中国核心生态区类型及土地利用数据集

Dataset of Classification and Land Use of the Ecological Core Areas of China

中国面临一系列生态环境问题,中国核心生态区数据可以为中国生态环境保护的战略决策和相关的科学研究提供参考。中国核心生态区数据集包括(1)中国6种生态核心区1∶100万比例尺地理信息系统数据,包括:水源涵养区、土壤保持区、防风固沙带、洪水调蓄区、河岸防护带和生物多样性保护区;(2)中国核心生态区2008年1,000m空间分辨率的土地利用栅格数据(耕地、林地、草地、湿地冰川、城乡工矿用地及生态容纳用地共6大类);(3)中国核心生态区土地利用变化(1980s、2008)统计数据。该数据集提取中国核心生态区的范围,划定维护国土安全的生态红线,为支撑中国生态环境安全领域研究提供基础数据。该数据集分别以.shp、.tif、.xslx格式存储,压缩后数据量7.14 MB。

Rapid social and economic development has led to a range of serious ecological and environmental problems in China.The development of a classification and land use dataset that encompasses ecological core areas nationally is therefore important to support decision making and provide a scientific basis for ecological restoration and environmental protection.The dataset presented here includes:(1)1∶1,000,000 scale data of ecological core areas encompassing water conservation area,soil conservation areas,as well as wind-breaking and sand-fixing area,flood regulation area,and riparian protection area and biodiversity conservation areas;(2)1 km scale grid data on land use within these areas in 2008;and(3)statistical data on land use changes between the 1980s and 2008.These data files encompass the spatial scope of ecological core areas within China,and delineate red lines for maintaining national ecological security.Dataset is archived in.shp,.tif,and.xslx formats with the data size of 7.14 MB in compress.
