- 摘要:
- 在全面分析影响农业水土资源复杂系统承载力变化诸多因素的基础上，初步提出了农业水土资源承载力的概念，选取27个与农业水土资源密切相关的承载力评价指标，为了解决评价指标过多引起的评价过程复杂性问题，将主成分分析法有效解决指标间多重相关性的特性和投影寻踪模型高效降维技术有效结合在一起，提出了投影寻踪主成分分析模型。将该模型应用于三江平原农垦建三江分局农业水土资源承载力综合评价中，取得了满意的结果，同时为农业水土资源承载力评价研究提供新的研究思路和研究方法。
- Abstract:
- On the basis of giving an overall analysis of factors influencing the changes of the carrying capacity of agricultural water and soil resources complex system, in this paper, the concept of the agricultural soil and water resources carrying capacity are preliminarily proposed. 27 evaluation indexes of the carrying capacity are selected. They are all closely related to the agricultural soil and water resources. In order to solve the problem of the evaluation process complexity that caused by the excess evaluation indexes. This paper puts forward Projection Pursuit Principal Components Analysis model. This model effectively combines the characteristic of Principal Components Analysis, which can solve multi-correlation among indexes effectively, and the technology of the Projection Pursuit model, which can reduce dimension efficiently. This model has already been applied in comprehensive evaluation of the agricultural water and soil resources carrying capacity at Sanjiang plain Jiansanjiang region. It gained the satisfactory result. Moreover, it provides a new idea and approach for the study on the evaluation of the agricultural water and soil resources carrying capacity.
