喀斯特石漠化与人文驱动因素相关性研究——以广西为例
|
摘要
【目的】定量研究广西石漠化与人文驱动因素的关系。【方法】根据部分典型石漠化县城的人文统计数据与石漠化情况开展相关分析。【结果】石漠化与农民人均纯收入、人均耕地和经济密度呈负相关;与人口密度和土地垦殖率呈正相关。石漠化与人文驱动因素相关性由大到小依次为土地垦殖率>农民人均纯收入>人均耕地>经济密度>人口密度。【结论】农民人均纯收入小于1 500元地区的石漠化发生率较高。不同人文驱动因素与石漠化分类结果的叠加分析,验证了农民人均纯收入与石漠化存在负相关。
【Objective】This paper quantitatively studies the relationship between Guangxi rocky desertification and human driving factors.【Methods】According to humanities and related statistical data in some typical rocky desertification counties and the rocky desertification situation,relevant analysis is carried out.【Results】The result showed that the rocky desertification was negatively correlated with rural per capita net income,per capita farmland and economic density,but it was positively correlated with population density and land reclamation rate.The correlation between rocky desertification and human driving factors in descending order as follows: Land reclamation rate> rural per capita net income>per capita farmland area> economic density> population density.【Conclusion】The incidence of rocky desertification in the region with a per capita net income of less than $ 1 500 is higher.The overly analysis of different humanities driving factors and rocky desertification classification results verified that the per capita net income of farmers was negatively correlated with rock desertification.
