| 摘 要： | 东北农牧交错区属于典型的环境脆弱区,也是我国水土流失、土地荒漠化和草场退化等生态环境问题最为严重的地区之一.深入研究其脆弱环境形成过程中自然因素和人为因素的作用孰轻孰重,对于在生态环境保护与治理过程中有针对性地采取相关政策和措施具有重要的实践价值.以内蒙古东部的通辽和辽宁西部的朝阳为样本点,选取反映自然和人为因素作用的指标,通过主成分分析法对该区域脆弱环境和土地荒漠化形成影响因素进行了比较研究.结果表明,人为因素的影响在东北农牧交错区脆弱环境和土地荒漠化发展过程中起主导作用,综合因素和自然因素的影响强度因地而异.

| Abstract: | There is a typical vulnerable environment in fanning-pasture zigzag areas of the Northeastern China. It is also a typical region in which the eeo-environment issues, such as the soil erosion, desertifieation, and the grassland degeneration are prominent. With the comparative study of the natural factors and the artificial ones that have the effects on the vulnerable environment of the researched areas, the public policies and the strategies for the environment protection in a comprehensive way would be in accordance with its characteristics. In this paper, the effective factors have been comparatively researched with the natural indicators and the artificial ones, and the methods of the principal component analysis. The indicators come from the Tongliao of Inner Mongolia Autonomous Region and the Chaoyang of Liaoning Province of China. The results make clear that the artificial factors play a leading role for the vulnerable environment and the desertifieation of the farming-pasture zigzag areas in the Northeastern China. The effects of the comprehensive factors and the natural ones are different owing to the regional characteristics. |
