黔南FAST周边典型喀斯特峰丛洼地石漠化生态修复模式研究——以平塘县克度镇刘家湾周边为例
Study of ecological remediation modes for rocky desertification in typical karst peak-cluster depression surrounding south Guizhou FAST: An example of the periphery of Liujiawan, Kedu town, Pingtang county
摘要
Abstract
Typical karst peak-cluster depressions are common in Pingtang county,southern Guizhou,where land rocky desertification is severe,and the eco environment was vulnerable,which are the primary factors limiting the local development and ecological security.To explore the model of rocky desertification ecosystem management and farmers' livelihood in this area,we make an analysis on the characteristics of soil and water resources and their spatial matching structure,and the rules of vertical differentiation between rocky desertification and ecological landscape.Then we present the suggestions as follows,(1)The technical model of peak-cluster depression biodiversity vine crown configuration,including mild rocky desertification vine+ arbor model,moderate rocky desertification vine + shrub model and severe rocky desertification vine + herb model;(2)Sectional governance (vertical differentiation) model and its technical system of the "lower repair and upper conservation" in peak-clusters steep land,including the mode of ecological public welfare forest natural recovery (care) on the summit,the mode of ecology economic forest-grass ecological restoration and agroforestry on upper and middle slopes of peak clusters,efficiency agroforestry management and water and soil conservation (ecological restoration) mode on the downhill of peak-clusters;(3) Filtering,Prunus salicina,Passifloracoerulea L.,Talinum paniculatum (Jacq.) Gaertn.,soil dry crisp jujube,Cerasushumilis,and other desert drought resistant suitable varieties.Analysis of the economic,social and ecological benefits of these varieties and their combination patterns shows that the economic benefit of Passiflora coerulea L.+ ice crisp plum,Passiflora coerulea L.+Talinum paniculatum (Jacq.) Gaertn.,Passiflora coerulea L.+ Prunussalicina+Talinum paniculatum (Jacq.) Gaertn.,abiodiversityconfigurationmode,is the best.It is also an effective way to resolve locally farmers' livelihoods in the depressions and has an important value to promotion and application in similar areas.关键词
