摘　　要： 本文选择业已完成农用地分等国家级汇总的冀豫鄂3省为研究区,基于农用地自然等别质量,探讨了农用地质量监测带的布设方法。在用格网法布设覆盖3省监测网的基础上,采用景观多样性指数法,计算监测网各条带农用地等别景观多样性指数,根据此指数并结合农用地资源的地域分异特征,最终筛选出一纵三横4条等别监测带:纵向监测带位于3省中部;3条横向监测带分别位于河北省北部地区、河南与湖北交界处、湖北南部地区。从空间特征上看,这一纵三横的4条监测带涵盖了3省所跨自然带,形状上构成一个不规则的"丰"字。从质量特征上分析,这4条监测带涵盖了3省农用地自然质量的全部等别,而且通过这种纵横交织的设计,当纵向监测带代表性不够时有横向监测带弥补,横向监测带代表性不够时有纵向监测带弥补,优越性较高。 Although land use monitoring technology both inside and outside of China is becoming more and more mature, monitoring is typically only used for land use type, desertifieation, or soil improvement. The monitoring of agriculture land quality has rarely been studied. One of the objectives of precision land management is to utilize existing technology to set up an agricultural land quality monitoring system, which would then contribute to an agricultural management reporting system. This study is based on the provinces of Hebei, Henan and Hubei, where work on establishing farmland grades has already been completed. The objective is to design monitoring belts which can function for the monitoring of farmland grades and offer reference points for national-scale monitoring of farmland grades and selection of monitoring points. First, the monitoring network was first set up. Then, we calculated the Shannon＇s Diversity Index （SHDI） for every monitoring belt in the network, and used these SHDI results and analyzed the results of the law of land resources distribution to choose four belts for land grade quality monitoring, one in the longitudinal direction and three in the transverse direction. The longitudinal direction monitoring belt is located in the center of these three provinces, and the three transverse direction monitoring belts are located in northern Hebei, the border of Henan and Hubei, and southern Hubei. These four belts compose a ＂丰＂ Chinese character. In terms of the composition of land grades, all four monitoring belts contain representative land grades from all three provinces. We suggest that using this method to set up land quality monitoring belts is superior because the two directions of belts provide representative samples for monitoring.
