运用3S技术
对吉林省境内的14个国家级自然保护区2000年和2010年的遥感影像进行了处理
分析了该地区2000-2010年期间土地利用/覆盖变化特征和生态系统服务价值的动态。结果表明
2000-2010年期间
研究区建设用地、草地和农田的面积有所增加
林地、湿地、水域和未利用地的面积均有所减少;该区域综合土地利用变化动态度为0.15%
空间动态度为0.43%;林地变化最缓慢
变化幅度低于区域平均变化水平。自然保护区生态系统服务价值降低9.95×10
8
元/a
降低率为1.73%。林地、湿地、水域和未利用地价值量有所降低
分别减少0.31%
6.78%
5.15%和8.96%
草地、农田价值量有所增加
分别增加了15.67%和5.13%。自然保护区的多种地类和多项生态系统服务价值均有下降趋势。
With 3S technology
characteristics of land use/cover change and variations of ecosystem services value from the year from 2000 to 2010 in 14 national nature reserves in Jilin Province were analyzed with remote sensing image. Results showed that during the period of 2000-2010
the area of construction land
grassland and farmland increased
while the area of forest land
wetland
water body and unused land decreased; the dynamic rate of integrative land use change from 2000 to 2010 was 0.15%
and the spatial dynamic rate of the region was 0.43%; forest land changed with the lowest change rate compared with the regional average change rate. With the rate of 1.73%
ecosystem services value in nature reserves decreased by 9.95×108 Yuan per year. Ecosystem services value of forest
wetland
water body and unused land decreased with the rate of 0.31%
6.78%
5.15% and 8.96%
respectively. Ecosystem services value of grassland and farmland increased with rate of 15.67% and 5.13%
respectively. Ecosystem services value of many land use types and multiple ecosystem services all decreased in different rates in the national nature reserves.
