近郊丘陵谷地高效农业综合开发研究

在剖析近郊丘陵谷地资源优势及利用问题的基础上，应用生态学和系统论原理及方法，以市场为导向，进行谷地资源的多目标线性规划，通过对区域系统物质循环、能量转化及经济效益的分析，提出“以鱼鸭结合为龙头，稳定果园面积，发展高效种植业”的总体规划方案，采取低产幼龄果园改良、名特优苗木繁育、池塘高产养殖和建立高效种植制度等技术措施，对谷地资源实行立体动态综合开发，建立较稳定的近郊丘陵谷地人工农业生态系统，取得显著的经济、社会和生态效益。

A STUDY ON INTEGRATED DEVELOPMENT OF AGRICULTURE WITH HIGH BENEFIT IN SUBURBAN HILLY GULLY AREA

Taking market demand as guidance, the multipurpose linear programme of resources was carried out according to the principle and method of ecology and systematic theory based on the analysis of resources superiority and problems of Xiao cun suburban hilly gully area. The overall scheme,“ taking freshwater fish and duck farming as a lead , stabilizing orchard areas, developing high benefit planting”, was formulated by analyzing material circulation, energy transformation and economic benefit of the ecosystem. The land resources were stereoscopically and dynamically developed by following measures: improvement of low yield and young orchard, cultivating famous and special tree species,breeding high yield pond product and establishing of high benefit planting. A steady artificial agricultural ecosystem was established, which achieved marked economic, social and ecologic benefits.
