宁夏县域绿色发展水平空间分异及影响因素

Spatial Variation and Relevant Influence Factors of Green Development Levels Among the Counties in Ningxia

基于2013年统计数据,综合运用熵值法、改进TOPSIS模型与障碍度模型对宁夏回族自治区县域绿色发展水平的空间分异及影响因素进行了实证研究。结果表明:宁夏绿色发展水平的内部差异明显,其中北部的西夏区、兴庆区、金凤区以及原州区的绿色水平贴近度远优于其他地区;中部的红寺堡区、盐池县和同心县的贴近度最差,绿色发展水平亟待提高。制约宁夏县域绿色发展的障碍因素具有地域差异性,黄河沿岸各县(区)、宁夏中部干旱各县(区)、南部六盘山各县(区)的绿色发展影响因素各有不同,针对不同地区提出不同的发展途径与对策,为研究区的绿色发展提供科学的参考依据。

Green development is the reflection and innovation in comparison to the traditional development mode,research on the green development,especially for Ningxia with the lagging economic development and fragile ecology,is particularly important. Basing the data of 2013,model of entropy,modified topsis and obstacle degree were used to study the spatial variation and relevant influence factors of green development levels among the counties in Ningxia. The results were as follows： The internal differences of green development levels in Ningxia were obvious,the values of close degree in District of Xixia, Xingqing, Jinfeng and Yuanzhou were far higher than other regions; well,the ones of Hongsipu area, Yanchi County and Tongxin County were the worst,whose green development levels need to be improved urgently. The factors restricting the green development of Ningxia had showed regional differences,and on the whole,counties（districts） along the Yellow River in Ningxia,counties（districts） in the drought of middle Ningxia,and that in southern Liupan Mountain have different limiting factors respectively. Furthermore,corresponding ways and countermeasures had better be taken in those areas,providing the scientific basis for the green development of Ningxia.
