耕地撂荒及其定量分析

Research on the Agriculture Land Abandoning and It's Quantitative Description

近二十多年来,耕地的弃耕撂荒现象在我国已多次出现,国内一些学者在实地调查的基础上,对耕地撂荒的现状、原因及解决途径等进行了一些具体的研究工作,但耕地撂荒的理论研究还很少见.本文对耕地撂荒的概念、类型和耕地撂荒的定量描述进行了系统的理论研究,结果表明:(1)耕地撂荒是指耕地处于一种未知性的荒芜或未充分利用时的状态.(2)可从不同角度出发对耕地撂荒进行不同的类型划分.(3)耕地撂荒的定量描述的研究,为农地撂荒对粮食安全和经济发展的影响的研究提供了理论依据.

The thing about agriculture land abandoning has happened in China about twenty years, some academicians have studied it case of some place, but them are not very entire. In this paper, we have studied the conception, styles and its quantificational characterization of agriculture land abandoning in this paper.
