西安市近二十年耕地"非农化"时空演变特征及影响因素
Spatial-temporal evolution characteristics and influencing factors of"non-agriculturalization"of arable land in Xi'an over the past two decades
摘要
Abstract
The phenomenon of"non-agriculturalization"of arable land is a significant challenge to farmland protection and food security in China.Studying the spatial-temporal patterns and influencing factors of this process can provide valuable insights for regional non-agriculturalization governance and farmland resource protection.This paper focused on Xi'an,using data such as land cover types and land use transition matrices to explore the spatial-temporal evolution characteristics of arable land"non-agriculturalization"and its influencing factors.The results show that from 2000 to 2020,the main land use types in Xi'an were arable land,forest,and built-up land.The areas with the most significant increases and decreases were built-up land(737.46 km²)and arable land(914.20 km²),with built-up land increasing by 119.30%.Over the past two decades,the total area of non-agriculturalized arable land was 744.91 km²,with the largest non-agriculturalization area found in Chang'an District,followed by Weiyang District(together accounting for 37.3%).The process was mainly distributed in areas with an altitude below 450 meters,a slope of less than 6°,and proximity to major roads.关键词
