- 摘要:
- 研究河北农牧交错区LUCC规律及其对生态脆弱性的影响，为研究区土地利用调控及生态环境恢复提供数据支持。从河北省农牧交错区选择典型样点作为研究单元，基于1987年，2000年和2007年的遥感影像，借助GIS技术手段和Fragstats软件，研究样点区LUCC及其对生态脆弱性的影响。结果表明：（1）研究区土地利用程度综合指数在2000年最高，1987-2000年为土地利用程度加重阶段，2000-2007年为减弱阶段。（2）1987-2000年斑块结构朝均一化方向发展，自2000年开始，SHDI和SHEI开始呈上升趋势。（3）1987-2000年LUCC导致了区域脆弱性程度加重，2000-2007年的LUCC大大减轻了区域生态环境脆弱性。土地利用/覆被变化直接影响区域的生态脆弱性，通过科学土地调控政策可以改变区域生态脆弱性。
- Abstract:
- The purpose of this paper is to study the LUCC law of agro-pastoral areas in Hebei and its effects on the vulnerability; provide data support for land use control and environment recovery. The method is to select typical areas from agro-pastoral areas as research unit in Hebei. Based on remote sensing of 1987, 2000 and 2007, the paper uses GIS and fragstats software to study the LUCC law of typical areas and its effects on the eco-vulnerability. The result show that: (1)The land use and land cover level of the highest composite index is 2000, 1987-2000 period increasing, 2000-2007 period decreasing; (2)In 1987-2000 period, plaque structure towards the homogenization of direction, SHDI and SHEI began rising since 2000; (3)LUCC leads to the aggravation of regional vulnerability in 1987-2000, which is opposite in 2000-2007. The conclusion is that the LUCC effects the regional vulnerability straightway; the regional vulnerability can be changed by scientific land control policy.
