土地整治前后耕地质量的等级评价:以凤冈为例

Grade Evaluation of Cultivated Land Quality Before and After the Application of Land Remediation Project:Taking the Program in Fenggang for Instance

为给贵州省开展土地整治提供理论依据,以贵州省凤冈县绥阳镇万亩土地整治项目为例,采用农用地分等修正方法,通过对整治前后耕地自然质量等级进行划分,评价土地整治工程设计和实施对耕地质量的影响程度。结果表明：整治前项目区耕地的自然质量分78.49分,耕地质量集中分布在3级;整治后耕地的自然质量分120.38分,耕地质量集中分布在4~5级。整治前后项目区耕地质量等级提升2~3级。

In order to provide the theoretical basis for land remediation in Guizhou,in this paper,taking million mu of land remediation project in Suiyang Town,Fenggang County of Guizhou as an example,the authors used the method of agricultural grade fixing to classify grades of farmland in project area before and after remediation,to clearly embody the incidence of land remediation project impact on the quality of arable land.The results concluded that the farmland natural quality score in project area is 78.49 before remediation,the quality of cultivated land is mainly distributed in 3rdlevel.The farmland in project area is 120.38 after remediation,the quality of cultivated land concentration distribution in 4~5thlevel.By comparative analyzing cultivated land quality before and after the remediation,which could found that the level of cultivated land quality was increased 2~3grades.
