中国中越边境地区耕地撂荒的时空特征与影响因素
SPATIO-TEMPORAL CHARACTERISTICS AND INFLUENCING FACTORS OF CULTIVATED LAND ABANDONMENT IN CHINA-VIETNAME BORDER AREAS
摘要
Abstract
This research is intends to reveal the spatial and temporal characteristics and influencing factors of the abandonment of arable land in the border areas,so as to provide a basis for promoting the effective utilization of arable land in the border areas and ensure national food security.On the basis of identifying the area of cropland abandonment in 15 counties(cities、districts)in China-Vietnam border areas,this study measured its spatial and temporal characteristics,and analyzed the influencing factors of cropland abandonment by using the geodetector model.The results showed that:(1)The area of cultivated land in China-Vietnamese border areas decreased from 5 975.45 km2 in 2000 to 5 955.54 km2 in 2020.(2)Cultivated land in China-Vietnamese border areas was mainly distributed in the Guangxi section,which had relatively flat terrain and better hydrothermal conditions;the average cultivated land area and the average cultivated land percentage in the Guangxi section were higher than those in the Yunnan section.(3)From 2000 to 2020,the area and rate of cultivated land abandonment in China-Vietnamese border areas showed an overall trend of decreasing,then increasing,then decreasing,then increasing;The spatial distribution characteristics of cultivated land abandonment were relatively significant,with the high value area of cultivated land abandonment from 2000 to 2005 mainly distributed in the Guangxi section,and the high value area of cultivated land abandonment from 2010 to 2020 mainly distributed in the Yunnan section.(4)Cultivated land abandonment in China-Vietnamese border areas was the result of the joint action of natural factors,socio-economic factors and location factors,of which natural factors were the basis,socio-economic factors were the main driving force,location factors played a profound role,and the interactions of the factors on the impact of the cultivated land abandonment were enhanced by a two-factor model.In conclusion,there is an Uneven spatial distribution of cultivated land abandonment in China-Vietnam border areas,with significant regional differences.Therefore,improving the financial subsidies for agricultural cultivation and mobilizing the motivation of border residents to engage in agricultural production is an important way of curbing the abandonment of arable land along the border.关键词
