摘要

长期来

由于建设方针上的失误

人口猛增

植被稀少

土壤瘠薄

“三料”俱缺

造成固原县水土流失相当严重

人民生活非常贫困。固原县经过1983—1985年的土地结构合理调整

生产力有较大提高

粮食产量明显增加

水土流失大幅度减少

群众收入净增两倍。结合全县的综合治理工作

确定了今后农林牧优化用地比例为1:1:3

农田中粮食作物、经济作物和牧草用地比例为5:1:2。建立良性农业生态模式的关键一环

是建立起一个合理高效的农林牧生态经济结构

孤立地就水土保持抓水土保持

解决不了这样一个全局性的问题。

Abstract

For a long time it caused soil erosion serious relatively and the peoplein Guyuan County with quite low living level for the increasing population

rare plantation

poor soil and shortage of a Three Materials ". Having beenadjusted during 1983 to 1985 in Guyuan County for the rational land usestructure

the region is now with a higher productivity

an increased grainoutput and soil loss reduced greatly

the net income of the mass there hasbeen increased for two times. In accordance with the comprehensive work

the ratio for optimized structure of land use of farming

forestry andhusbandry is determined as 1:1:3. The key step to establish a soundagroecological model is to develop an available and efficient ecologicaleconomic structure of farming

forestry and husbandry.But if the soilconservation is performed only for soil conservation

it is impossible to solvethe problem as a whole.
