京津沙源区草场沙退化综合整治模式探讨

Inquiry into Comprehensive Realignment Model of Sand and Degeneration Process of Grassland in Sand Source Areas around Beijing and Tianjin

为尽快落实中央政府关于做好京津周边地区防沙治沙工作,遏制土地继续沙化和沙漠蔓延扩展,加大草原沙化、退化治理力度,减轻风沙对京津周边地区危害的战略布署,开展浑善达克沙地草场沙化、退化综合整治技术试验示范研究,旨在全面了解浑善达克沙地草场沙化、退化形成演化规律,探索解决畜草矛盾的途径和草原生态环境综合整治及水—草—畜持续发展的模式,研究开发和引进一批草场沙化、退化综合整治和水草资源合理利用的技术,并通过治理工程将各种技术组装集成示范推广,使新模式实体化,从而为我国草场防沙、治沙生态保护及区域群众脱贫致富提供决策依据和技术支撑。

In order to implement the strategic plan of the central government as soon as possible, which about, how to do well in preventing and controlling sands around Beijing and Tianjin,how to contain the continual sandy process and desert spreading, how to strengthen the controlling level of sand and degeneration process and how to lighten wind and sand damage to the areas around Beijing and Tianjin, we start the test demonstration study of comprehensive realignment technology of sand and degeneration process of the grassland in the Hunshandakesand. The intent of it is to completely comprehend the forming and evolution law of sand and degeneration process of the grassland in the Hunshandakesand, to seek new way for solving the contradiction between animal and grass, to seek comprehensive realignment model of the grassland ecology environment,to seek sustained development model of water, grass and animal and to research,develop and introduce comprehensive realignment technologies of sand and degeneration process of grassland and rational use technologies of water and grass resources. Finally,through controlling engineering to compose,integrate demonstrate and spread all these kinds of technologies and make our new model become reality, which will provide decision basis and technology support for preventing and controlling sand of grasslands and leading the regional masses to get out of poverty and become rich.
