Crops eco-economic adaptability evaluation based on ecological-market potential capacity

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 eco-economic adaptability of different crop-region combinations was established,the calculative method of the single ecoeconomic 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.By comparative analysis,the result could be used as guidance for preferential order of productive arragement of crops among different regions.The method could be used as eco-economic adaptability for different crop-region combinations.
