江汉平原粮食产量空间格局分析

Analysis of Spatial Pattern of Grain Output in Jianghan Plain

基于湖北省第一次地理国情普查数据、基础地理信息数据和统计年鉴等资料,采用洛伦兹曲线、Moran指数等对江汉平原典型4个粮食主产区监利县、洪湖市、仙桃市、潜江市的粮食产量空间格局进行了分析和研究。研究表明:①洪湖市耕地资源与粮食产量间的对应关系较为平等,粮食单产稳定,粮食生产空间聚集显著;②监利县、潜江市与仙桃市的耕地、粮食产量表现出极弱空间相关性或无相关性,粮食生产能力相对较差,耕地资源及产量未表现出空间聚集优势。该结论可为农业部门制定农业生产计划和发展规划提供良好的数据支撑,为地理国情普查成果的应用提供借鉴。

Based on geographical conditions census data for the first time,basic geographic information data and statistical yearbook of Hubei province,the spatial pattern of grain output in four typicalmajor grain producing areas(Jianli,Honghu,Xiantao,Qianjiang)is analyzed and researched using Lorentz curve,Moran index and so on.The results show that:(1)the corresponding relationship between the cultivated land resource and food production of Honghu is relatively equal,with stable yield of grain,and significantly grain production space aggregation;(2)there is very weak spatial correlation or no correlation between the cultivated land resource and food production of Jianli,Qianjiang,and Xiantao,with relatively poor grain production capacity,and no space gathered advantage of cultivated land resource and yield.This conclusion can provide good data support for agricultural production planning and development planning.
