中俄黑龙江跨境流域1990-2020年土地覆盖与耕地资源时空变化
Spatio-temporal Changes of Land Cover and Cultivated Land Resources in the Cross-border Amur River Basin Between China and Russia from 1990 to 2020
摘要
Abstract
The cross-border Heilongjiang Basin between China and Russia,rich in land resources,holds significant potential for food production in Northeast Asia.Grasping its past land cover and cropland changes is important for regional agricultural resource development and utilization.This study addresses the chronic lack of awareness of land cover and agricultural resources in the area.Utilizing the GlobeLand 30 and GLC_FCS 30 datasets the study obtained 30-meter resolution land-cover data for the years 1990,2000,2010,and 2020.Models such as the land use transfer matrix,attitude of motivation,and intensity of change were employ to analyze land cover changes in the Amur River Basin,with a focus on cropland resources and their comparison between China and Russia.The analysis reveals that forest land is the dominant land cover type,followed by grassland,cropland,water,construction land,and unutilized land.From 1990 to 2020,the cultivated land area initially decreased,then increased,with the most significant change occurring between 1990 and 2000.While the period 2010-2020 is a period of more significant increase in the area of cultivated land.Comparative analysis between China and Russia shows that the area of cultivated land in the Chinese part of the Heilongjiang Basin is much larger than that in the Russian part,and the drastic change of cultivated land in the Chinese part of the Heilongjiang Basin during the period of 1990-2000 is much higher than that of cultivated land in the Russian part of the Heilongjiang Basin,but it has been weakened significantly in the last 20 years.From the common point of view,the trend of cropland change in both the Chinese and Russian regions within the Heilongjiang basin is first decreasing and then increasing,the difference is that the total area of cropland in the Chinese region decreases and the total area of cropland in the Russian region slightly increases during the period from 1990 to 2020.The study found that population migration,urbanization,land reform and shortage of funds may be the main reasons for the changes in arable land resources,and accordingly,it suggests recommendations for future development and utilization.关键词
