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。
