在分析了400多种作物的生态适应性资料的基础上,构建了作物生态适宜性评价指标体系。根据生态因子的限制原理,在生态因子的稀缺性指数的基础上,提出了作物生态适宜性分析的变动赋权原理和方法,克服了传统主观赋权法的不足,形成了较为系统的作物地域生态适宜性评价分析方法。实例分析结果表明,该方法评价结果符合实际。
On the basis of analyzing the ecological adaptability data of more than 400 kinds of crops, the index system of crop ecological suitability was established. According to the restriction principle of ecological factors, based on the index of scarcity of ecological factors, the paper puts forward the principle and method of variable empowerment of crop ecological suitability analysis, overcomes the shortcomings of the traditional subjective weight method and forms a relatively systematic crop region Ecological suitability analysis and analysis method. The result of example analysis shows that the method is in good agreement with the actual situation.
