- 摘要:
- 生态环境受多种因素的影响和制约。本文针对淮河流域桐柏-大别山区的自然条件和人为干扰状况构建该区域的生态脆弱性评价指标体系，利用地理信息系统软件ARCINFO的空间主成分分析功能，进行定性与定量相结合的研究，对淮河流域桐柏-大别山区的生态脆弱性进行综合评价。并运用ARCINFO的空间分析功能，得到不同生态脆弱性的面积与空间分布规律，为制定相应的治理与生态恢复对策提供科学依据。
- Abstract:
- The ecological environment is affected and restricted by many factors. According to the natural conditions and the human disturbance conditions in the Tongbai-Dabie Mountain Area of Huai River Basin, this paper builds the Eco-environmental vulnerability evaluation index system, and evaluates comprehensively the Eco-environmental vulnerability of the Tongbai-Dabie Mountain Area of Huai River Basin qualitatively and quantitatively, based on the principal component analysis of the GIS software -ARCINFO. Then using the spatial analysis of GIS, it is easy to find the area and spatial distribution of different vulnerability grades.This study provides a scientific basis to make policies of governance and ecological restoration.
