城市周边永久基本农田划定次序研究——以潜江市为例

Study on the Delimitation Order of Permanent Basic Farmland around City--Taking Qianjiang City as an Example

以湖北省潜江市城市周边地区为例,运用LESA评价方法,对研究区城市周边永久基本农田的划定次序进行了实证探索。研究表明,潜江市城市周边耕地自然质量总体较好,永久基本农田综合质量的优劣主要取决于耕地立地条件的差异。其中,综合评价质量条件最优的耕地面积为27.55 km^(2),占区域总面积的18.24%,可作为永久基本农田的优先划入区;综合评价质量条件较优的耕地面积为100.64 km^(2),占区域总面积的66.65%,可划为适宜划入区;综合评价质量条件较差的耕地面积为22.80 km^(2),占区域总面积的15.11%,可划为永久基本农田的后备划入区。在此基础上,对实际工作中永久基本农田的划定提出了建议。

Taking the surrounding areas of Qianjiang City in Hubei Province as an example,LESA evaluation method was used to empirically explore the delineation order of permanent basic farmland around the city in the study area.The research showed that the natural quality of cultivated land around Qianjiang City was generally good,and the comprehensive quality of permanent basic farmland was mainly due to the differences in the site conditions of cultivated land.Among them,the cultivated land with the best comprehensive evaluation quality conditions was 27.55 km^(2),accounting for 18.24%of the total area,which could be used as a priority area for permanent basic farmland.The cultivated land with better comprehensive evaluation quality conditions was 100.64 km^(2),accounting for 66.65%of the total area,which could be divided into suitable areas.The cultivated land with poor comprehensive evaluation quality was 22.80 km^(2),accounting for 15.11%of the total area of the region,which could be classified as a reserve area for permanent basic farmland.On this basis,some suggestions were proposed for the delineation of permanent basic farmland in practical work.
