Research On Suitability Evaluation Of Site Selection For Hybrid Rice Seed Production In D County

In the adjustment of rural industrial structure,land is the most crucial carrier.Land suitability evaluation is a basic evaluation of land use,and it is related to the success of industrial structure adjustment.The land suitability assessment is a comprehensive assessment of the land resource quality in the target area for a specific purpose of industrial restructuring.The high yield of hybrid rice led to a rapid increase in the demand for hybrid rice seeds.The hybrid rice seed production industry is an advantageous industry for the adjustment of the industrial structure of D County in the target area.In this study,Yaahp(AHP),ArcGIS GIS and Global Mapper software were used to select indicators such as geographical and environmental conditions,natural ecological and climatic conditions,and external social and environmental conditions that affect the location of hybrid rice seed production bases.From altitude,topography slope,and landform slope Based on the impact factors such as soil type,soil type,light duration,relative humidity,effective accumulated temperature,policy investment environment,population labor force status,and regional economic development level,establish a data model,and use the impact factors for the selection of the hybrid rice seed production base in the D district of the target area.Analytic Hierarchy Process(AHP)evaluates and obtains corresponding weights.Then,the entropy weight method is used to optimize the impact factor evaluation to make it more relevant to reality.In the Arcgis GIS,the above influencing factors for re-weighting the entropy weight method were superimposed using a multiple regression model to obtain a comprehensive evaluation digital map and statistical data of the land suitability of the hybrid rice seed production base.The results of this study provide scientific basis for the development of hybrid rice seed production in D County,the development target area,and avoid the loss caused by blindly selecting the base.This will not only produce huge economic benefits,but will also bring great social benefits.
