摘　　要：In China with such a large population and few land, the problem of arable land is particularly prominent. While the amount of arable land per capita is small, the quality of arable land is declining. Compared with the decreasing arable land, the decline in the quality of arable land is invisible and hard to be detected. But the impact is no less than the amount of arable land reduced, and ~;hanges in the quality of arable land pose a serious threat to ecological environment and socio- economic development. Against the background of high-intensity development and the amount of arable land decreasing, the research of monitoring of arable land quality is of great realistic significance.耕地问题在我国这样一个人多地少的国家显得十分突出,主要表现在2个方面:一是人均耕地少,二是耕地质量下降。相对于耕地面积的有形减少而言,耕地质量的下降是隐性的,不易被人们所察觉,但其影响却绝不亚于耕地数量减少,耕地质量的变化正在对生态环境和社会经济发展构成严重的威胁。在高强度开发背景和耕地数量持续减少的态势下,对耕地质量监测的研究具有重要的现实意义。
