南京地区农业资源的综合评价研究

SYNTHETIC ASSESSMENT OF AGRICULTURAL RESOURCES IN NANJING AREAS

客观、准确地评价地区农业资源，对于农业资源的开发和利用具有重要意义。本文从系统论观点出发，将地区农业资源分成自然资源和社会资源，在能够较好地反映系统结构特征、不同样点差异及满足易于收集、便于数量表示和定量处理等基本要求的基础上，选择了若干评价指标。利用综合指数法、区位商法等评价方法，对南京地区的主要农业资源（土地资源、气候资源与社会资源）进行了定量分析，并在此基础上，利用资源优势度分析法进行了综合评价。结果表明，南部小区的农业资源具有整体优势，南部和中部的资源利用较为合理，北部小区则具有较为丰富的后备资源。最后，根据各地资源要素的不同组合，简要给出了较适宜的开发途径，为该地农业资源的进一步开发与利用提供了依据。

It is very important to assess the regional agricultural resources objectively and accurately for both their development and use.In this paper,on the basis of some assessment indexes reflecting the structural features of agricultural resource system and the differences in different sites and meeting the demands of feasible to collect and easy to express and process quantitatively,the agricultural resources are divided into natural and social resources.Some assessment methods,i.e.,integrated index method,location quotient method are used to quantitatively analyze and assess the main agricultural resources such as land,climatic and social resources in Nanjing areas.The analysis method of resources dominant degree is used to evaluate synthetically.The result shows that the agricultural resources are dominant in the southern part,their development and use are relatively rational in the southern and middle parts,and the reserve resources are plenty in the northern part of Nanjing areas.At last,based on the combination of the resource components in different sites,the suitable development approaches of the resources is discussed,which can be taken as the basis to further develop and use the resources in this region.
