田阳县贫困村空间分异及其对土地利用程度的响应

以行政村作为研究单元,基于2015年田阳县各类土地利用和贫困度相关数据,建立贫困度指标体系,采用皮尔逊相关系数与二元局部Moran的I指数等方法,分析该县贫困村空间分异特征,并研究其对土地利用程度的响应。结果表明:贫困村在空间分布上受到生产生活条件的影响,呈现出一定的连片特征,空间分异明显;贫困村的土地利用程度与该地区的贫困程度具有显著负相关关系,说明土地利用程度的提高会降低区域贫困度。

Spatial Differentiation of Poverty Villages and Its Response to Land Use in Tianyang

Land is the most basic material resources of human production and life, and the main source of poverty is the lack of material living conditions, the lack of land resources is an important factor leading to poverty. Studying how to make full use of limited land and tap its potential is important for poverty alleviation in poverty-stricken areas. In this study, Tianyang County in the Youjiang River Basin was selected as the research area, and the administrative village was used as the research unit. Based on the data of land use and poverty gap in 2015, the poverty index system was established, and the Pearson correlation coefficient, the local Moran's I and other methods were used to analyze the spatial differentiation characteristics of poverty-stricken villages and determine their response to the degree of land use in the county. The results show that the poverty villages are mainly affected by production and living conditions in spatial distribution, with some contiguous characteristics and obvious spatial differentiation. The degree of land use in the key poverty-stricken villages has a significant negative correlation with the degree of poverty in the county, which means that the improvement of land use would reduce the regional poverty.
