湖南土壤的地理分布规律

湖南属于中亚热带常绿阔叶林红壤地带.境内自然条件复杂,从而影响红壤的发商和分布具有水平分布规律;东、南、西三面环山,土壤的发生和分布显示着明显的垂直分布规律(即红壤—黄红壤—山地黄壤—山地黄棕壤—山地灌丛草甸土)。加以非地带性因素的影响,还具有多种结构形式的区域分市规律。研究和分析土壤地理分布规律,对土壤资源的综合开发利用具有重要的现实意义。

GEOGRAPHIC DISTRIBUTION OF SOILS IN HUNAN PROVINCE

Hunan province is part of the mid-subtropical evergreen broadleaf forest red earth zonal. It' s natural condition is complicated. The development and distribution of Red Earth shows the horizontal distribution. As Hunan is surrounded by mountains on the east. south and west, there the genesis and distribution of soils manifests marked vertical distribution. (e.g.Red Earth-Yellow-red Earth-Mountain Yellow Earth-Mountain Yellow-brown Earth-Mountain Shrubby-meadow Soil). In addition, many types of repional distribution are due to intrazonal factors. Study and analysis of the law of the soils geographic distribution is important for the complex erploit and utilization of soli resources in Hunan.
