摘要:
土地整理通过各项工程措施,使得耕地的利用类型及土壤理化性质等发生变化。如何评价土地整理后的新增耕地质量,是当前研究的热点和难点。本研究针对土地整理工程措施的特点,以福建省长泰县为例,研究土地整理后耕地质量评价的参评指标,以及土地利用系数、经济系数的计算方法,以期提高土地整理项目区耕地质量评价的精度。研究结果表明:土地整理区新增耕地质量评价指标需考虑土地整理工程措施影响较大的土壤保水保肥能力、水源类型、田块平整度等;同时,需对《农用地分等规程》中土地利用系数、土地经济系数的计算方法进行改进,以提高新增耕地质量评价结果的准确性。
Abstract:
Due to alternations made on farmlandsunder the “land consolidation project,”it is inevitable that the utilization and soil physicochemical properties of the landsundergo varied degree of changes.Reliable evaluation on the quality of newly created landsfor cultivation has become a rather urgent,and yet difficult,task for the scientists and management involved in the projects.Based on the typical project requirements,using Changtai county in the province as an example,a case study was conducted in an attempt to establish an evaluation methodology that could effectively predict the outcome for a given land consolidation project.Indices on theland quality,as well as calculation of the utility and economic coefficients for the farmland,were carefully studied.It was concluded that the fertilizer retention of soil,source of water supply,evenness of field,and calculation of coefficientswere among the areascould be furtherimproved.
