摘要

在对土地利用信息提取的基础上

运用土地利用变化强度、动态度、土地利用程度、生态系统服务价值对陕西省神木县土地利用时空演变特征及其生态响应进行了分析。结果表明

2000-2010年神木县土地利用类型转换较快

土地利用程度明显减弱

耕地、草地、林地、水域、工矿用地、建设用地和未利用土地的变化强度分别达到-1.687%

0.782%

0.469%

-0.033%

0.067%

0.086%和0.316%。2000-2010年神木县生态系统服务价值呈增长态势

10 a间增加了0.94亿元

同期耕地生态价值减少了3.95亿元

林地和草地分别增加了3.47和1.92亿元

而水域和未利用土地的生态价值变化不大。空间上

北部乡镇生态系统服务价值以下降为主

而南部乡镇以增长为主。

Abstract

Taking the TM images in 2000 and 2010 as data resource

combined with land use change quantity analytical method and GIS and RS technology

the authors analyzed land use changes and its ecological response in Shenmu County of Shaanxi Province from 2000 to 2010 by adopting the comprehensive land using dynamic degree

land use degree and ecosystem services value(ESV). The result showed that the land use patterns transformed quickly and land use degree reduced in Shenmu County from 2000 to 2010

in which the intensity of land use change of cultivated land

grassland

woodland

water area

industrial land

urban construction and unutilized land reached-1.687%

0.782%

0.469%

-0.033%

0.067%

0.086%

and 0.316%

respectively. Total value of ecosystem services increased 94 million yuan in Shenmu County from 2000 to 2010. Meanwhile

the ESV of woodland and grassland increased by 347 million yuan and 192 million yuan respectively. On the contrary

the ESV of cultivated land decreased by 395 million yuan

and water area and unutilized land had the smallest change. Spatially

total value of ecosystem services in the northern township mainly declined

at the same time

in southern township

it mainly rose.
