基于生态恢复理论和植物群落演替的规律 ,在延安试验区布设固定标准地和临时标准地 ,在植物群落动态变化调查的基础上 ,分析了退耕还林和封育后 ,阳坡、半阳坡植物群落动态变化的趋势 ,重点分析了白刺花 ( Sophora viciifolia)在黄土丘陵沟壑区植物群落演替中的动态变化及其作用 ,提出利用白刺花采用二步到位的方法促进植物群落顺行演替 ,快速恢复生态系统。
Based on the theory of ecological restoration and the succession of plant community, fixed standard and temporary standard were laid in Yan’an experimental area. Based on the investigation of plant community dynamic change, after the conversion of farmland to forest and enclosure, Slope vegetation community dynamics. The dynamic changes of Sophora viciifolia plant community succession in the hilly-gullied Loess Hilly and Grenad area were analyzed emphatically. It was proposed that the two-step method was used to promote plant community Successive succession, rapid recovery of ecosystems.
