绵阳市水稻种植适宜性区划分析

Regionalization Analysis of Rice Planting Suitability in Mianyang

我国是农业大国,粮食产量一直位居世界前列,水稻是我国赖以生存的主要粮食作物之一。随着全球气候变暖、自然灾害频发和大陆板块移动,农业种植区划做出相应的调整。为绵阳市水稻种植提供精细化服务和优化种植结构,选择气候、地形、土壤三大类因子对绵阳市水稻种植适宜性区划进行分析,结合绵阳市实际情况,将区划指标划分为适宜性、较适宜性和不适宜性,建立绵阳市水稻种植适宜性区划模型。结果表明,绵阳市南部地区适宜种植水稻,北部地区受高海拔等地形影响,不太适合水稻种植。

China is a major agricultural country,with grain production consistently ranking among the top in the world.Rice is one of the prime food crops that China relies on for survival.With global warming,frequent natural disasters,and continental plate movement,agricultural planting regionalization should be adjusted according to natural resource change.To provide refined services for rice cultivation in Mianyang and optimize the cultivation structure,three major categories of factors,namely climate,topography,and soil,were selected to analyze the suitability zoning of rice cultivation in Mianyang,and the zoning indexes were classified as suitable,more suitable and unsuitable,and a suitability zoning model for rice cultivation in Mianyang was established.The results showed that the southern area of Mianyang was fit for rice cultivation,while the northern area was not for rice cultivation due to the influence of topography,like high altitude.
