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10 679.93 hm2，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:
The optimal allocation of cultivated land plays a key role in alleviating the contradiction between the urban construction land expansion and cultivated land protection, which is one of important issues for the process of national land and resources development. Taking Xinbei District,Changzhou City, as a case study, we constructed a comprehensive evaluation system of cultivated land protection value from the perspectives of natural endowments, quality condition of cultivated land, spatial pattern, site conditions and planning and forecasting results. Then, based on the results from standardizing 18 index values with S type fuzzy membership function, the optimal allocation of cultivated land was explored by combining with grey correlation model and the ideal point method. The cultivated land in the research area was divided into five parts by depending on the principle of maximum similarity. And the predictive value of the demand for cultivated land in Xinbei District in 2020 was set as the threshold value to determine the optimal distribution for cultivated land. The results show that the number of the cultivated land of the first four ranks exceeded 10 679.93 hm2, the simulation value of the demand of cultivated land of Xinbei District in 2020, so the corresponding cultivated land was regarded as the best area of cultivated land. Chunjiang Town and Menghe Town are the key areas of cultivated land protection because of their large areas or superior quality.
