2013-2015年京津冀新增耕地时空特征与来源分析
Spatial-temporal Characteristics and Source Analysis of Newly Increased Cultivated Land in Beijing-Tianjin-Hebei Region from 2013 to 2015
摘要
Abstract
Based on the data of newly increased cultivated land from 2013 to 2015 at the district and county-level in Beijing-Tianjin-Hebei region,the whole feature of the newly increased cultivated land,the feature of different types newly increased cultivated land were explored,and the newly increased cultivated land was analyzed from the perspective of different sources in-depth.The research methods included gravity center model,Gini-coefficient,geographic concentration and some methods of statistical analysis.Research results showed that from 2013 to 2015,all of the new cultivated land in the Beijing-Tianjin-Hebei region was mainly concentrated in the middle east plain,western mountainous areas and the northern plateau areas.Analyzing the newly increased cultivated land in different years,the area of the newly increased cultivated land in Beijing-Tianjin-Hebei region was decreased first and then increased;the gravity center was transferred from north-east to south-west.And the newly cultivated land was highly concentrated.Gry land was mainly cultivated land types in Beijing-Tianjin-Hebei region,but the newly increased irrigated land was mainly newly increased cultivated land type.The largest proportion was land consolidation' s newly increased cultivated land in rural.The main source of the newly increased cultivated land was grassland,so that ecological problems were becoming more prominent.On this basis,reasonable suggestions were put forward for Beijing-Tianjin-Hebei region in the future land remediation work.It was suggested that the Beijing-Tianjin-Hebei project should adjust measures to local conditions in the future,increase water efficiency,and pay attention to the construction of ecological civilization.关键词
