摘要
当今世界生态与环境的诸多问题中,脆弱生态系统综合整治是焦点之一.深入探析我国干旱半干旱地区生态综合整治的节水、植物防沙治沙、微生物固沙、机械沙障、化学固沙、盐碱化防治等技术,集成并优化了8种综合整治模式,包括绿洲水平衡调控模式、绿化防沙模式、生态退耕防沙治沙模式、机械-生物治沙模式、农林复合沙产业模式、水土系统改良模式、自然力恢复模式和自然保护区建设模式.最后,基于人地关系理论、可持续发展理论和生态循环经济理论,构建了区域生态重建互动模式,实施路线包括产业互动、区域互动、敏感点互动、绿色制度互动等4个环节.这些均可为防止我国干旱半干旱地区脆弱生态系统进一步退化和生态综合整治实践提供理论基础.
In ecological and environmental problems of present world,ecological vulnerability is one of focusing issues.There are six main comprehensive techniques in the arid or the semi-arid region of China,including water-saving irrigation,desertification prevention and control plant,microorganism filtration,mechanical sand barrier setting,chemical sand-fixing and salinization control.In this study area,eight models have been integrated and optimized,including the regulating-control of water balance in oasis,the greening project,ecological deterioration,the combination of mechanical sand barrier setting and organisms implantation,the sand industry of agro-forestry,the system amelioration of water-soil,the restoration by natural process,and the management of natural reserve.At last,based on three theories of man-land relationship,sustainable development and eco-cycle economy,a regional coordinative mode of ecological reconstruction is founded.Its system consists of the following four sectors： industrial interaction,regional interaction,sensitive spots interaction and green institution interaction.These conclusions will provide a theoretical basis for both preventing further deterioration of an ecosystem and an environment comprehensive realignment in an arid or a semi-arid region of China.
