相对资源承载力综合分析与评价——以江苏省沭阳县为例

以江苏省典型的农业大县——沭阳县为研究单元,分别以江苏省、宿迁市为参照区域,对沭阳县相对土地资源承载力、相对经济资源承载力和综合承载力进行了综合分析和评价;并以沭阳县为参照区域,探讨了37个乡镇相对资源承载力的地域差异.研究表明,沭阳县综合承载力小于实际人口,呈超载状态;相对土地资源承载力对综合承载力的贡献率在50%以上,而经济资源承载能力有待加强;相对资源承载力呈现一定的空间差异特征,35%的乡镇相对超载,65%的乡镇相对富余.

GENERAL ANALYSIS AND EVALUATION OF THE RELATIVE CARRYING CAPACITY OF RESOURCES: A CASE STUDY IN SHUYANG COUNTY OF JIANGSU PROVINCE

electing Shuyang which is typical agriculture county in Jiangsu Province as the research object,taking Jiangsu Province and Suqian city as reference zones respectively,the relative carrying capacity of land resources,economy resources,and synthetic capacity have been comprehensively analyzed and evaluated.At the same time,taking Shuyang county as the reference zone,regional difference of the relative carrying capacity of resources,involving with 37 villages and towns of Shuyang county is also disscussed.then the results are as follow: synthetic capacity is lower than the real population of Shuyang county,presenting in the overloading situation;the contribution rate of the carrying capacity of land resources to the carrying capacity of synthetic resource is above 50 percent,however,the relative carrying capacity of economy resources is still to be strengthened.The regional differences of the relative carrying capacity of resources in Shuyang county are extremely significant,the population of 35 percent villages and towns is relatively overloaded,and 65 percent is relatively sufficient.
