【摘要】：运用2004-2013年31个省级行政区农村环境相关数据,构建农村环境质量评价体系,利用ESDA—GIS探究时空分异规律,再运用门槛回归模型探讨农村经济发展与环境质量的门槛效应。结果表明,我国农村环境质量存在明显时空分异特征:时间上,近10年来我国农村环境质量综合评价指数由2004年的51.01上升至2013年的52.89,可见我国农村环境质量总体改善,且东部及南方部分经济发达地区近年农村环境质量改善效果显著;空间上,我国农村环境质量自东向西趋好,存在空间集聚性,北方农村环境质量普遍优于南方。此外,我国农村环境质量与农村经济发展存在门槛效应:农业发展水平对我国农村环境质量的影响呈先负向相关后正向相关的双重门槛关系;工业发展水平负向影响农村经济,跨过门槛值后,负向影响减小;农户收入与农村环境质量呈先负向相关,跨过门槛值后正向相关的单门槛关系。从农业发展水平、工业发展水平和农户收入3个方面来看,发展农村经济对改善农村环境质量具有显著的效果。因此,应着力围绕"生产环境绿色高效、生活环境整洁舒适、生态环境山清水秀"目标,全方位多角度重点改善我国东部及南方地区农村环境质量,并大力发展农村经济,从而全面改善农村环境质量。
[Abstract]:Based on the relevant data of rural environment in 31 provincial administrative regions from 2004 to 2013, the evaluation system of rural environmental quality is constructed, and the temporal and spatial differentiation law is explored by using ESDA-GIS, and the threshold effect of rural economic development and environmental quality is discussed by using threshold regression model. The results show that there are obvious spatial and temporal differences in rural environmental quality in China. In the past 10 years, the comprehensive evaluation index of rural environmental quality in China has increased from 51.01 in 2004 to 52.89 in 2013. The overall improvement of rural environmental quality in China can be seen. The improvement of rural environmental quality in eastern and southern developed areas is remarkable in recent years. In space, the rural environmental quality of our country tends to be better from east to west, there is spatial agglomeration, and the rural environmental quality in north is generally superior to that in south. In addition, there exists threshold effect between rural environmental quality and rural economic development in China: the impact of agricultural development level on rural environmental quality is negative correlation and then positive correlation, and industrial development level negatively affects rural economy. After crossing the threshold, the negative effect was reduced, and the peasant household income was negatively correlated with the rural environmental quality first, and the single threshold relationship was positive after crossing the threshold. From three aspects of agricultural development level, industrial development level and peasant household income, the development of rural economy has remarkable effect on improving rural environmental quality. Therefore, we should focus on the goal of "green and efficient production environment, clean and comfortable living environment, beautiful ecological environment", focus on improving the rural environmental quality in the eastern and southern regions of China, and vigorously develop the rural economy. In order to improve the overall quality of the rural environment.
