摘要
中国西南地区人口-资源-环境的矛盾非常突出,贫困与生态恶化的双重压力使该地区的生态环境脆弱程度进一步恶化。对西南地区做出客观公正的生态脆弱性评价,可对该地区实现社会经济的可持续发展提出科学依据。本文以云南、贵州为例,根据云贵两省的生态环境特点,对导致两省生态环境脆弱程度恶化的主要因素——地质、气候、经济等因素进行统计分析并做出综合评价,最后再根据综合评价指数进行结果分析与讨论,为缓解云贵两省生态环境脆弱程度的进一步恶化提出合理化建议。
Although southwest China has abundant natural resources, the situation of population, resources and environment is very critical. Poverty and environment degeneration reaches to ecological fragility level. Evaluating ecological fragility of southwest China objectively and justly, can present scientific authority for this region with realizing sustainable development of social economy. Taking Yunnan & Guizhou for instance in this paper, numerated and analyzed orderly the main factors: geological, climate, economic which caused ecological fragility level deterioration according to the environment character of two provinces, and then take the comprehensive evaluation.
