河西走廊的发展历史记录了人与荒漠相互影响、相互斗争的过程。荒漠化防治与生态恢复遏制了荒漠的扩展蔓延,改善了农业生产环境,促进了经济、社会的发展。然而,由于气候变化、河西走廊的特殊地理位置与自然条件、人对生态系统的过分干扰与对资源的不合理利用,荒漠化问题依然存在,部分地区荒漠化还在加重。气候变暖加剧了生态系统的脆弱性,增加了农业生产的风险性,使荒漠化防治与生态恢复面临严峻的挑战。建议引入综合生态系统管理理念,完善法规政策框架,将应对气候变化纳入地方发展规划;实施参与式监测与评估,使所有利益相关者平等、全面参与;构建节水型社会,提高公众节水意识;完善生态补偿制度;发展农牧民可持续生计,促进荒漠区经济、社会与环境可持续发展。
<<The development history of the Hexi Corridor is a process of growth and decline due to the mutual influence and struggle between man and desertification. The desertification control and ecological restoration in recent decades have curbed the expansion and spread of desertification,improved the agricultural production environment,and promoted economic and social development. However,due to climate changes,and special geographical location and natural conditions of the Hexi Corridor,excessive human interference with ecosystem and unreasonable use of resources,the causes of desertification still exist and lead to increasing desertification in some areas. Warming exacerbates the vulnerability of ecosystems and increases the risk of agricultural production,thus making desertification control and ecological restoration a serious challenge. It is suggested to introduce the concept of integrated ecosystem management,improve the capacity of regulatory and policy frameworks,integrate climate change response into local development planning,implement “participatory” monitoring and evaluation,and enable equal and full participation of all stakeholders;build a water conservation society and raise public awareness;improve the ecological compensation system;develop sustainable livelihoods for farmers and herders;and promote sustainable economic,social and environmental development in desert areas.
