【摘要】：高标准基本农田建设是实现耕地数量管控、质量管理和生态管护的重要手段。为探究方便高标准基本农田建设决策及实施的以行政村为决策单元的耕地质量评价和建设分区方法,该文以曲周县土地综合整治项目区为例,构建基于区域最优耕地质量水平的村域耕地质量均匀度评价模型并基于新的耕地质量观从地力质量、工程质量、空间质量、生态环境质量和美学质量5个方面构建村域耕地质量均匀度评价指标体系,通过对各指标分级赋值、加权求和计算村域耕地质量均匀度,分析区域耕地质量差异及障碍因素指标限制性,按照先易后难的原则进行高标准基本农田建设时序分区。结果显示:项目区各行政村耕地质量均匀度值处于7.03~22.40之间,行政村之间差异明显;项目区限制性较强的障碍因素多为中等和低改造难度指标,局部存在高改造难度指标。将项目区划分为重点建设区(710.11 hm~2)、次级建设区(2 199.04 hm~2)、一般建设区(975.47hm~2)和有条件建设区(1101.07 hm~2)4部分,建设难度由易到难;评价模型和指标体系可以满足对村域耕地质量的评价和障碍因素诊断,可方便后续建设决策,该研究可以为高标准基本农田建设实践作参考,为相关研究提供新的思路和方法。
[Abstract]:The high standard basic farmland construction is to realize the cultivated land quantity control. In order to explore the convenience of high standard basic farmland construction decision-making and implementation of the administrative village as the decision-making unit of arable land quality evaluation and construction zoning method. Taking Quzhou County land comprehensive renovation project area as an example, the evaluation model of village cultivated land quality uniformity based on the regional optimal cultivated land quality level is constructed, and based on the new concept of cultivated land quality, the land quality and engineering quality are analyzed. Five aspects of space quality, ecological environment quality and aesthetic quality are used to construct the evaluation index system of the quality uniformity of cultivated land in the village area. The quality uniformity of the cultivated land in the village area is calculated by grading and assigning the indexes, and calculating the evenness of the quality of the cultivated land in the village area by weighted summation. The difference of regional cultivated land quality and the restrictive index of obstacle factors were analyzed. According to the principle of first easy and then difficult to carry out the high standard basic farmland construction time series partition. The result shows that the farmland quality uniformity value of each administrative village in the project area is between 7.03n22.40, and the difference between the administrative villages is obvious; Most of the restrictive obstacle factors in the project area are middle and low difficulty index of reconstruction, and there are high difficulty index in local reconstruction. The project area is divided into the key construction area (710.11 hmm2). The secondary construction area is 2199.04 hmHm ~ (2), and the general construction area is 975.47 Hm ~ (2)) and the conditional construction area is 1101.07 hm~2)4 part. Construction difficulty from easy to difficult; The evaluation model and index system can satisfy the evaluation of farmland quality in village area and the diagnosis of obstacle factors, and can be used as a reference for the practice of high standard basic farmland construction. To provide new ideas and methods for related research.
