永久基本农田划定中耕地质量条件与耕地立地条件协同体系研究

耕地质量条件与耕地立地条件是永久基本农田划定的重要基础和保障，二者不可或缺，相互协同。该项目重点开展三方面内容研究：（1）一是在分析和构建适宜于永久基本农田划定的耕地质量评价体系与立地条件评价体系基础上，以综合指数模型开展耕地质量评价与立地条件评价的影响机制分析，建立永久基本农田划定的耕地质量与立地条件评价标准体系；（2）二是开展耕地质量条件与耕地立地条件二者之间协同关系研究，通过采用多元正态回归分析方法和柯布—道格拉斯生产函数法分析耕地质量条件、耕地立地条件与粮食产能的相互作用关系，并以耦合协调度模型建立和检验二者之间的协同关系；（3）三是在省级尺度建立永久基本农田划定的耕地质量条件与耕地立地条件协同体系，并选取典型县区进行实践检验，进而制定适宜山地区、平原区和低山丘陵区永久基本农田划定的耕地质量与立地条件协同标准体系。研究成果可为全国尺度永久基本农田划定提供理论基础和技术方法支撑。

The good quality and site conditions of farmland are important foundation and guarantee for the planning of permanent basic farmland, which are necessary and synergistic for each other. Three contents are carried out In this research, including:(1)On the basis of analysis and construction of farmland quality and site conditions evaluation system suited for the permanent basic farmland, the standard evaluation system of farmland quality and site conditions would be established by comprehensive index model which are used in analyzing the influencing mechanism of each other.(2)It would also carry out the research of synergic relations of the farmland quality and site conditions, and the interaction relations of farmland quality and site conditions and grain production are analyzed by using multiple regression analysis and cobb-douglas production function methods, and the synergic relations of the farmland quality and site conditions are established and checked by coupling degree model.(3)In province scale, the synergic system of farmland quality and site conditions would be established on the basis of synergic ratio research ,which would also be checked in some typical countries. In the last, the standard synergic system of farmland quality and site conditions would be established uniformly suiting for the permanent basic farmland planning in mountain area, plain area and low hilly area, the research results could provide theoretical foundation and technique support for the permanent basic farmland planning in national scale.
