随着社会经济的发展，我国的城镇化进程不断加速，于此同时产生的生态破坏、地质灾害、环境污染等生态地质环境问题也日益突出。因此，生态地质环境承载力的研究，对一个地区城镇化及经济的发展都有一定的指导意义。本文在对生态地质环境承载力内涵及影响因素分析的基础上，根据城市经济区生态地质环境的普遍情况，分层次探讨了生态地质环境承载力评价指标体系的内容。把生态地质环境承载力评价指标体系分为3个子系统，它们分别是：地质环境子系统、生态环境子系统和社会环境子系统。并且根据宁夏沿黄经济区的特点，从正负两个方面对3个系统内的各个指标进行阐述，并对其影响程度进行分析打分。然后，利用GIS技术的空间叠加技术，对宁夏沿黄经济区的生态地质环境承载力进行分级。此区域共分为三级：第一级为适宜建设区，第二级为适度控制建设区，第三级为中度控制建设区。
隨著社會經濟的髮展，我國的城鎮化進程不斷加速，于此同時產生的生態破壞、地質災害、環境汙染等生態地質環境問題也日益突齣。因此，生態地質環境承載力的研究，對一箇地區城鎮化及經濟的髮展都有一定的指導意義。本文在對生態地質環境承載力內涵及影響因素分析的基礎上，根據城市經濟區生態地質環境的普遍情況，分層次探討瞭生態地質環境承載力評價指標體繫的內容。把生態地質環境承載力評價指標體繫分為3箇子繫統，它們分彆是：地質環境子繫統、生態環境子繫統和社會環境子繫統。併且根據寧夏沿黃經濟區的特點，從正負兩箇方麵對3箇繫統內的各箇指標進行闡述，併對其影響程度進行分析打分。然後，利用GIS技術的空間疊加技術，對寧夏沿黃經濟區的生態地質環境承載力進行分級。此區域共分為三級：第一級為適宜建設區，第二級為適度控製建設區，第三級為中度控製建設區。

With the development of society and economy, the process of urbanization continues to accelerate, ecological destruction, geological disasters, environmental pollution and other ecological problems are increasing. Study on eco-geological environment carrying capacity(EECC) of a region's economic development and urbanization has a certain importance. Through analysis of connotation and factors of EECC, we discuss system speciifcations of EECC by combining general conditions of ecology environment of city economic zone. Indicator system of EECC divided into three respects, which are geological, ecological and social environment. According to the characteristics of economic zone along the Yellow River in Ningxia, we explain index of three systems and scores on impacts. Economic zone along the Yellow river in Ningxia are divided into three levels by spatial analysis of GIS. The best level area is suitable for building, the secondary area is moderately suitable for building, and the third area is not suitable for building unless more safety protects are available.
