摘要
将乌兰布和沙漠绿洲分为绿洲生态经济核心区、绿洲-荒漠生态缓冲区和自然荒漠生态恢复区3个功能区,基于各功能区的地貌、植被、土壤及沙害特征与沙源,立足因地制宜规划、因害设防整治的设计思想,提出"流沙固阻带、封沙育草带、防风阻沙带、绿洲防护林网"四带一体的综合防治体系防御流沙入侵,采用工程、农艺等应急措施体系控制绿洲内土壤风蚀和零星流沙的危害,为人工绿洲沙害的综合控制提供了科学依据。
Oases in Ulan Buh Desert can be divided into three function areas,namely oasis eco-economic core area,oasis-desert ecological buffering area and desert ecological restoration area from oasis core to edge.Based on field observation of topography,vegetation,soil,sand disasters and sand sources of different functional areas,a comprehensive control technology system with four parts,which were ＂fixing shifting-sand zone＂,＂ fencing dune for grass recovery zone＂,＂preventing wind and stopping sand zone＂,and ＂oasis protection forest network＂,was proposed to defend the intrusion of shifting sand.An emergency measure system,including engineering and agricultural measures,was proposed to reduce the damage of wind erosion and scattered shifting sand in oases.The study provides a scientific basis for comprehensive control of sand disasters in artificial oases.
