摘要
运用生态学、生态经济学、系统工程的原理,对水土保持型速生高效乔灌草配置模式及其土壤侵蚀控制效能作了初步研究。遵循"因地制宜,适地适树"的原则,结合水土保持、速生、高效等功能,选择乔灌草品种,设计了5种植被配置模式,在每种模式中,用标准径流小区、米级小区和钉子法测定土壤侵蚀量;用溅蚀杯法测定土壤溅蚀量;用In-situ技术监测土壤养分的动态变化。通过研究,结合生态、经济和社会效益,对各个模式的土壤侵蚀控制效能进行定量化综合评价,选出最佳模式,利于推广应用。
The water and soil conservation type of fast-growing and high-effective arbor,brush and grass disposal mode and its soil erosion control efficacy were preliminarily studied with ecology,ecological economics and system engineering theories,5 vegetation disposal modes were designed with selecting the arbor ,brush and grass varieties,in combination with the water and soil conservation,fast-growing and high-effective functions,and according to the principle of Adjusting the Measures to Local Conditions,and Right Tree on Right Site. The quantified comprehensive value of every modes of soil erosion control efficacy was conducted,and the optimal mode was selected through the studies,and in combination with the ecological,economic,and social benefit,which did help to the popularization and application.
