由中国科学院长沙农业现代化所承担的《岷江上游半干旱区农林牧合理结构研究》课题,于1991年4月14日由中国科学院武汉分院主持,通过成果鉴定。 本研究系国家“七五”重点攻关课题《岷江上游半干旱区水源涵养林水土保持林营造技术与小流域综合治理研究》的一个子专题。研究工作自1987年开始,以四川省茂汶县大沟小流域(静州村)为试点,对生态环境脆弱、自然条件恶劣、经济社会发展缓慢的岷江上游半干旱河谷山地系统农林牧合理结构与布局体系,进行了全面、系统、深入的研究。运用生态学、经济学等理论技术原理和系统分析方法,通过资源、社会、经济调查、环境辩识与系统诊断、总体优化与重点论证,建立了人口、资源、经济和土地利用、技术等多种动态数学模型,进行计算机动态仿真模拟试验。
The topic of “Research on the Rational Structure of Agriculture, Animal Husbandry and Animal Husbandry in the Upper Minjiang River Upper Reaches of Arid Regions” undertaken by Changsha Institute of Agricultural Modernization, Chinese Academy of Sciences was presided over by Wuhan Branch of the Chinese Academy of Sciences on April 14, 1991 and passed the appraisal of achievements. This research is a subtopic of the national “Seventh Five-Year Plan” key research project, “Research on Technology of Water and Soil Conservation Forest and Integrated Management of Small Watersheds for Water Conservation Forest in Upper Reaches of Minjiang River.” Since 1987, a pilot project has been carried out in Dagou Small Watershed (Jingzhou Village), Maowen County, Sichuan Province. Since the establishment of the semi-arid valley in the upper reaches of the Minjiang River, the rational agriculture, forestry, animal husbandry and rational structure of the mountainous areas have been characterized by fragile ecological environment, poor natural conditions and slow economic and social development. With the layout system, conducted a comprehensive, systematic and in-depth study. Using such theories and techniques as ecology and economics and systematic analysis methods, we have established a system of population, resources, economy, land use and technology through resources, social and economic investigation, environmental identification and system diagnosis, overall optimization and key argument. Kinds of dynamic mathematical model, the computer simulation test.
