基于标准样地国家级汇总的耕地质量动态监测点构架研究

Framework of the arable-land quality dynamic monitoring sites through national gathering of standard farmland

该文以黑龙江、吉林、辽宁、山西、河南、安徽、湖南、湖北、江西中部九省为研究区域,以农用地省级汇总成果为主要数据来源,首次将标准样地国家级汇总成果与耕地质量动态监测相结合,对基于标准样地国家级汇总的耕地质量监测点的选取进行初步探讨,完成中部九省标准样地国家级汇总数据库建设,并分析九省国家级标准样地在不同等别及二级区上的分布情况,在此基础上,进行基于标准样地的耕地质量动态监测点的选取,最后,对标准样地体系提出参考性建议。

The study areas are limited in the following nine provinces of central China. Heilongjiang, Jilin, Liaoning, Shanxi, Henan, Anhui, Hunan, Hubei and Jiangxi, and the main data sources are based on the results of provincial gathering of arable land classification. It is the first time that the results of national gathering of standard farmland, and the arable-land quality dynamic monitoring have been combined. Moreover, this paper puts forward the preliminary discussion about the arable-land quality dynamic monitoring sites selection based on the national gathering of standard farmland establishes the database of the central nine provinces gathering of standard farmland, and analyzes the distribution of standard farmland, according to different grades and different secondary regions. On these bases, after selecting the arable-land quality dynamic monitoring sites on standard farmland, the authors provide some referential advice for the system of standard farmland.
