| 摘 要： | 为了对耕地保护技术层面措施进行定性定量研究,测度土地利用动态监测在省级层面的耕地保护效果,以1999—2008年省级面板数据为基础,借助STATA软件分别通过聚类稳健标准差下固定效应模型、随机效应模型和混合OLS模型进行估计,选择最优拟合结果。F检验,B-P检验,Hausman检验显示固定效应模型拟合结果最优,以该模型对土地利用动态监测的耕地保护效果进行测度。结果表明:土地利用动态监测的实行对减少耕地面积下降有显著作用;土地利用动态监测比率每提高1%,能减少耕地流失188.05 hm2;从土地利用动态监测耕地保护效率来说4个直辖市要高于其他省份。

Arable Land Conservation Effects of Land Use Dynamic Monitoring in China |

| Abstract: | This study aimed to evaluate the arable land conservation effects of land use dynamic monitoring , which was regarded as a technological approach , on provincial level quantitatively and qualitatively .Based on the panel data collected from 1999 to 2008, this article applied fixed-effects model, random-effect model and pooled OLS model to estimate the question .After testing the results , the fix-effect model was finally chosed to explain the question .On that basis , this paper estimated the effect of dynamic monitoring of land use in arable land conserva -tion and the results are as follows:The implementation of dynamic monitoring technology of land use does contribute to the decline in land loss and every 1%increase in the dynamic monitoring rate of land use will bring a 188.05 hm2 decline in land loss .As for arable land conservation efficiency of dynamic monitoring of land use , those of the four centrally administered municipalities in China shows a higher rate than that of other provinces and municipali -ties. |
