由内蒙古水科所、水利局水保处和奈曼旗水保办、青龙山水保站等单位协作承担的“系统工程在水土保持综合治理中应用研究”成果,最近通过技术鉴定。这项研究以奈曼旗寒山小流域综合治理开发为试点,在对小流域自然环境和土地资源调查分析评价基础上,运用生态经济学的观点,系统工程的理论,线性规划的方法,微型电子计算机手段,以治理开发经济效益最大为目标,建立了有217个决策变量、45个约束方程的土地合理利用开发数学模型,提出治理措施镶嵌配置、农林牧综合发展的优化方案。通过三年实施,在25.2km~2的寒山小流内,治理度达到81%,土壤流失量减少72%,粮田亩产由49.2kg提高到129.2kg,粮食总产增加141%,农林牧总收入增加78.2%,人均纯收入增加56.2%,初步形成低耗,高效的小流域生态经挤系统,基本达到高速度、高标准、高效益的治理
By the Inner Mongolia Institute of Water Resources, Water Resources Bureau and the Naiman Banner Water Conservation Office, Qinglongshan Soil Conservation Station and other units to undertake the collaboration of “Systems Engineering in Soil and Water Conservation Comprehensive Management Research” results, recently passed the technical appraisal. Based on the investigation and evaluation of the natural environment and land resources in the small watershed, this research uses the comprehensive management of Nanyimen Banner Hanshan Small Watershed as a pilot project. Based on the analysis of the ecological environment, the theory of system engineering, Computer tools, with the goal of maximizing the economic benefits of development and management, a mathematic model of land rational use and development with 217 decision variables and 45 constraint equations was established, and the optimized plan of mosaic configuration of governance measures, integrated development of agriculture, forestry, animal husbandry and animal husbandry was proposed. After three years of implementation, in the small mountain stream of 25.2km ~ 2, the degree of harnessing reached 81%, the amount of soil loss decreased by 72%, the grain yield per mu increased from 49.2kg to 129.2kg, and the total grain output increased by 141% The total revenue increased by 78.2% and net income per capita increased by 56.2%, initially forming a low-waste and high-efficiency eco-economic squeeze system in small watersheds and basically achieving high-speed, high-standard and high-efficiency governance
