基于GIS环江县桑蚕农业气候区划

文章采用1981-2010年的气候资料、基础地理信息数据,根据气候学和农业气象学原理,建立光、温、水等气候要素值的计算模拟模型,实现了无气象观测站点气象要素的定量推算,模拟农业气候资源的时空分布。通过分析环江县温度、水分、光照等气象要素与桑树生长、桑蚕饲养的关系,找出对桑蚕生产具有重要影响的气候因子,进行环江县桑蚕区划,为气候资源利用、农业结构调整、特色农业发展提供科学依据。

Agroclimatic regionalization of silkworm based on GIS in Huanjiang County

Based on principal of climatology and agrometeorology, meteorological data 1981-2010 and basic geographical information data have been adopted to set up simulation model of climatic factors such as light, temperature and water etc., and to realize the quantitative calculation without climatic factor data in observation station, which can simulate the space-time distribution of agrometeorology resource. By means of analysis on the relationship between temperature, water and light factors in Huanjiang and the mulberry growth ＆ silkworm feeding, the meteorological factors impacting significantly silkworm pro- duction can be found for silkworm regionalization in Huanjiang, which will provide scientific basis ofr meteorological resource, agricultural structure adjustment and featured agriculture development.
