耕地质量等别监测研究——以图们市为例

Monitoring of Cultivated Land Quality Grade:A Case Study of Tumen City

以图们市为研究对象,在耕地质量等别渐变区域,选取监测单元,对引起各监测单元耕地质量变化的主要因素进行了监测,并通过插值法计算出国家利用等别,并在所获得的监测单元数据监测结果的基础上,对耕地等别与产能变化情况进行了动态监测评价,为明确耕地质量内涵,科学保护耕地提供了依据。

Tumen city was used as the research object,the monitoring units were selected from the regions with graduallychanging cultivated land quality grade,and the main factors causing the changes of cultivated land quality in each monitoring unit were monitored.The grade of national land use was calculated by using interpolation method.On the basis of obtaining the monitoring data results of each monitoring unit,this paper conducted the dynamic monitoring evaluations of cultivated land quality grade and productive capacity changes in Tumen city,which could provide basis for clarifying the connotation of cultivated land quality and for scientifically protecting cultivated land.
