摘要
针对云南省元谋干热河谷区的土壤退化严重，运用专家系统建立了土壤退化指标和分类体系，并在典型区进行了土壤退化现状调查和分类评价。结果表明：在该区发展旱地农业必须以防治土壤退化为中心，采取改善农区生态环境条件、调整旱地农业结构、改土培肥等对策。并初步总结了在以上认识指导下，试验高效复合农林生态系统——旱地胡同式农业的结果。这是一项防治干热河谷土壤退化、发展旱地农业的成功模式。
Soil degradation is the serious in Yuanmou dry and hot valley, Yunnan province. By use of expert system, the indices and classification system of soil degradation were set up in this region. The countermeasures of dryland farming development were put forward to control and prevent soil degradation in the region, which included improving ecologic environment, regulating the structure of dryland farming and fertilizing soils to reenforce soil ability against degradation. Moreover, the model to construct the high efficient compound agro forestry system——Alley Compound Agro forestry System, was proposed to be applied in dry and hot valleys. The experiments had demonstrated that the system was a successful model controlling soil degradation and developing dryland agriculture.
