摘要
本文以图像遥感解译为主 ,结合野外实际考察 ,并通过抽样验证完成。在对生态环境界定和赋予内涵的基础上 ,根据区划目的、原则和所选取的指标体系 ,从生态环境分类入手 ,经过从上向下续分和由下向上合并的反复磨合过程、专家集成模拟 ,对西北五省(区 )生态环境做了全面的综合分区研究 ,并针对所存在的生态环境问题 ,提出生态环境保护和建设的对策 ,为西北五省 (区 )实施西部大开发生态环境监测、治理、建设和规划提供科学依据。
This paper is completed mainly using the method of remote sensing images interpretation and combining with the method of field investigation and species test. After giving the conception and connotation of ecological environment in Northwest China according to the principle and purpose of the appraisal indexes selected, a all sided integrated demarcation is made through reiteration running-in the division from up to down and the mergence from down to up on the basis of classification of ecological environment in Northwest China. Finally, this makes a proposal for protection and building measure of ecological environment in Northwest China. These results provide scientific basis for monitoring, harnessing, construction and planning of ecological environment in Northwest China.
