淮北平原农业区耕地面积时空格局演变与驱动力分析
Spatial-temporal pattern evolution of cultivated land area and its driving forces of agricultural areas in Huaibei plain
摘要
Abstract
[Objective]The present study explored spatial-temporal pattern evolution and its driving forces of agricultural areas in Huaibei plain,in order to provide scientific basis for sustainable utilization and management of cultivated land resources.[Method]Based on the relevant statistical data from 2000 to 2013,this paper analyzed spatial-temporal pattern evolution of cultivated land acreage of agricultural areas in Huaibei plain,Anhui province.The main indexes included dynamic degree of cultivated land,cultivate land index and gravity center model of cultivated land.Then the driving forces in the spatial-temporal pattern evolution of cultivated land area were studied by principal component analysis.[Result] (1)Total cultivated land area in Huaibei plain and most counties (district) decreased to a small extent during 2000-2013,but cultivated land area in the rest parts increased.(2)The space distribution pattern of cultivated land area in the west was more than that in the east.The gravity center of cultivated land shifted from northwest to southeast during study period.But for the whole study area,the migration range was not large.And it did not affect the whole distribution pattern.(3)Principal component analysis showed that main driving forces were social economy and urbanization,capability of agricuhural production and natural disasters.[Suggestion]Following suggestions are proposed:strengthening the protection for existing cultivated land resources,rational development of reserve land resources;relying on science and technology to improve agricultural production capacity,improving land management policies to ensure the vital interests of farmers;controlling population and establishing the consciousness of cultivated land resources crisis.关键词
