山西省生态地理区域研究

Study on Eco-geographical Regions of Shanxi

生态地理区域系统研究是根据代表自然界的生物和非生物要素地理相关性的比较研究和综合分析,按照自然界的地域分异规律,划分或合并而形成不同等级的区域系统。其成果可以成为制定治理措施的基础。山西省地处黄河中游、黄土高原的东部,华北大平原的西侧,特殊的气候和土壤条件造成了山西省特有的生态问题。在传统生态地理区域分类指标体系的基础上,应用SPSS10.0聚类分析法,引入所需的指标,在剔除贡献不显著的指标后,进行聚类。根据各生态地理区域的自然条件,划分成六大生态地理区域,并且在DeltaDraph5.0的支持下做出山西省的生态地理区域分区图,指出各区域的生态问题,并提出生态建设的主要方向和措施。

The eco-geographical system is a hierarchical regional system divided or combined based on geographic-related comparison and integrated analysis of biological and non-biological factors on the earth＇s surface according to natural distributing laws. Related researches can serve as the basis for working out government strategies. Shanxi Province is situated at the middle reaches of Yellow River, the eastern part of loess plateau, on the west side of the North China great plains, and the special climate and soil conditions have created unique ecological problems for Shanxi Province. This paper uses cluster analysis of SPSS 10.0 on the basis of the traditional eco-geographical regionalization designated classification system, with the non-significant contribution indexes being removed. According to variations of natural conditions, the eco-geographical system of Shanxi province is divided into 6 eco-geographical regions, and the zoning plans are made by using DeltaGraph 5.0. The region＇s ecological problems and the ecological strategies of each region are briefly described.
