• It has the basic features of strong market competition , obvious economic benefits , large production scale and high industrial specialization . the development of characteristic resource in a region is based on the advantages of local resources - both naturally and anthropogenicaly . therefore , its target is to explore the advantageous local resources to produce high quality agricultural goods to meet the demands of markets and society for the return of high profits
  本文在探讨特色农业概念、内涵及其主要影响因素的基础上，构建了以农业资源禀赋、农产品综合比较优势、作物生产生态适宜性3大指标类15个二级指标48个三级指标为核心的特色农业评价指标体系及其相应的评价方法，结合gis平台，建立了特色农产品区域布局的实施方案，并结合案例以5年生产数据和15 30年气候统计数据进行了实证分析。
• In order to evaluate the eco - economic adaptability of crops production , the concepts and calculative methods of ecological potential capacity and market potential capacity were put forward , the dynamic threshold value system of the indexes for the economic adaptability of different crop - region combinations was established , the calculative method of the single eco - economic adaptability indexes , the comprehensive eco - economic adaptability indexes which reflects the principle of minimum factor and the apparent eco - economic adaptability indexes and the regional comprehensive apparent eco - economic adaptability indexes which reflects practical situation of crops production were built up . 12 representative counties in jiangsu province were selected to analysis , and 77 combinations of eco - economic adaptability indexes , apparent eco - economic adaptability indexes of crop - region and 12 regional comprehensive apparent eco - economic adaptability indexes were obtained
  摘要为评价作物生产的生态经济适宜性，提出了生态容量潜势和市场容量潜势的概念和计算方法，建立了适用于不同作物地区组合的、各指标阈值具有动态性的生态经济适宜性评价指标阈值体系，构建了单生态经济指标适宜性指数及反映最小因子定律的综合生态经济适宜性指数、表现作物生产现状的表观生态经济适宜性指数和地区综合表观生态经济适宜性指数的计算方法。
• The social economic information includes country economic information , agricultural material market information and natural calamity information . the agricultural science and technology information includes variety information and crop production management information . the agricultural net resource includes agricultural book and periodical information , agricultural expert information , agricultural research organization information , patent and achievement information and so on
