华东地区作物授粉依赖度和作物多样性的时空演变研究
Spatial-temporal evolution of crop pollination dependence and crop diversity in East China
摘要
Abstract
Based on data from 2000 to 2020 on the sown area of crops in East China,this study con-structed indicators of crop pollination dependence and crop diversity.By integrating GIS spatial analysis and statistical methods,the study explored the temporal and spatial patterns of crop pollination dependence and crop diversity in East China,as well as their correlation.The results are as follows.(1)The agricultural structure in East China was primarily dominated by grain crops,with the area sown to cash crops experien-cing the most significant change,decreasing by approximately 45.90％over the study period.(2)Both crop pollination dependence and crop diversity exhibited fluctuating and decreasing trends over time,with nota-ble differences among provinces.(3)Spatially,crop pollination dependence followed a"high in the north,low in the south"pattern,while crop diversity showed a"high in the east,low in the west"pattern.(4)There was a significant positive correlation between crop pollination dependence and crop diversity across East China,though the strength of this correlation varied among provinces.This study provides a reference for understanding regional crop pollination needs and agricultural structural changes.关键词
