摘要
生态承载力是人类社会发展的基础,是一个区域是否可持续发展的限制性因素,尤其是在生态环境脆弱的干旱区内陆河流域更显得尤为重要。为了探讨我国干旱区内陆河流域生态承载力时空格局变化,以疏勒河流域为研究区,基于GIS平台,研究疏勒河流域生态承载力时空演变特征,并进一步利用主成分分析定量分析自然因子和人类活动因子对其时空演变的影响。分析结果表明,人口密度和建成区面积是促进疏勒河流域生态承载力提高的主要因素,说明经济社会发展有利于促进区域生态承载力提升。
Ecological carrying capacity is the basis of human social development and the limiting factor of sustainable development of a region,especially in the arid area with fragile ecological environment.In order to explore the spatial-temporal pattern of ecological carrying capacity of inland river basin in arid area of China,the spatial-temporal evolution characteristics of ecological carrying capacity of Shule river basin are studied based on GIS platform,and the effects of natural factors and human activity factors on the spatial-temporal evolution are further analyzed by principal component analysis.The results show that:population density and built-up area are the main factors to improve the ecological carrying capacity of Shule river basin,which indicates that economic and social development is conducive to promoting the improvement of regional ecological carrying capacity.
