摘要/Abstract

摘要： 为确定不同地貌区建设项目耕地占用比例上限,为耕地保护和用地审批提供依据,选取湖北省为研究区,收集其2013—2022年交通、水利、能源3类项目用地数据,按平原、丘陵、山地划分地貌。采用分位数作为阈值参数,分析各类项目在不同地貌区的耕地占用比例,确定合理上限并计算节约率。结果表明,湖北省3类项目在不同地貌区耕地占用差异明显,交通类耕地占用面积最多（占比为89.48%）,空间分布呈平原(68.3%)>丘陵(21.33%)>山地(10.37%)的趋势;经分位数阈值法确定,平原区能源类耕地占用比例上限达99.19%,而山地水利类仅40.17%;规划项目验证表明,在保证大部分项目通过率在78.05%及以上时,可实现最高12.76%的耕地节约率。由此可知,阈值法确定的建设项目耕地占用比例上限能有效控制耕地占用。建议将70%~90%作为不同地貌下各类项目耕地占用比例上限的参考阈值,结合项目具体情况选取参数,平衡保护与发展,为化解湖北省耕地保护与建设占用矛盾提供决策依据。

Abstract: In order to determine the upper limit for the proportion of cultivated land occupied by construction projects in different geomorphological zones, and to provide a basis for cultivated land protection and land use approval, Hubei Province was selected as the study area, and its land use data for three types of projects, namely, transport, water conservancy and energy, were collected from 2013 to 2022, and the geomorphology was divided according to plains, hills and mountains. The quartiles were used as threshold parameters to analyse the proportion of cultivated land occupied by each type of project in different geomorphological zones, determine the reasonable upper limit and calculate the saving rate. The results showed that there were obvious differences in the cultivated land occupation for the three types of projects in different geomorphological zones in Hubei Province. The area of cultivated land occupied by transportation was the highest (the proportion of 89.48%), and the spatial distribution showed a decreasing gradient of plains (68.3%)>hills (21.33%)>mountains (10.37%). Based on the quantile threshold method, the upper limit for the proportion of cultivated land occupied by the energy in the plains area reached 99.19%, while that of the mountainous water conservancy category was only 40.17%. The validation of the planning project showed that the maximum saving rate of 12.76% of cultivated land could be achieved while ensuring an approval rate of 78.05% or higher for most projects. In conclusion, the upper limit for the proportion of cultivated land occupied by construction projects determined by the threshold method could effectively control the cultivated land occupation. It was recommended to take 70%-90% as the reference threshold for the upper limit of the proportion of cultivated land occupied by various types of projects in different geomorphological zones, and select parameters in combination with specific project conditions to balance protection and development, so as to provide a decision-making basis for solving the contradiction between cultivated land protection and construction occupancy in Hubei Province.
