【摘要】：如何通过配置耕地的空间布局,缓解城市建设用地扩张与耕地保护之间的矛盾,是国土资源利用过程中必须重视的问题。研究以常州市新北区为例,首先,从耕地的自然禀赋、质量条件、空间形态、区位条件和规划预测五个方面入手,共选取18个指标因子,构建了耕地资源保护价值评价指标体系;然后,利用S型模糊隶属度函数标准化指标数值,并综合运用灰色关联分析和理想点逼近法,以实际地块为单元,对评价结果进行优劣排序;最后,根据最大相似性原理,将研究区内的耕地分为五级,以预测模拟的目标年份耕地需求量为基准,确定耕地空间上的最优分布位置。研究结果表明,2020年新北区耕地需求量的模拟值为10 679.93hm~2,前四级耕地总量能够满足其要求,故将相应耕地划入最优区域。春江镇和孟河镇分别以其广大的区位优势和优良的耕地质量成为耕地保护的重点区域。
[Abstract]:How to alleviate the contradiction between the expansion of urban construction land and the protection of cultivated land by allocating the spatial distribution of cultivated land is a problem that must be paid attention to in the process of utilizing land and resources. The study takes Xinbei District of Changzhou City as an example. Firstly, 18 index factors are selected from five aspects: natural endowment, quality condition, spatial form, location condition and planning prediction of cultivated land. The evaluation index system of cultivated land resources protection value was constructed. Then, the S-type fuzzy membership function is used to standardize the index value, and the grey correlation analysis and ideal point approximation method are synthetically used to sort the evaluation results with the actual block as the unit. Finally, according to the principle of maximum similarity, the cultivated land in the study area is divided into five levels, and the optimal spatial distribution of cultivated land is determined based on the prediction of cultivated land demand in the simulated target year. The results show that the simulated value of cultivated land demand in New North District in 2020 is 10679.93hmm2, and the total amount of the first four grades of cultivated land can meet its requirements, so the corresponding cultivated land is divided into the optimal area. Chunjiang Town and Menghe Town have become the key areas for cultivated land protection with their vast geographical advantages and excellent cultivated land quality.
