中国农业生态工程的主要技术类型

农业生态工程是生态农业建设的重要内容，是实施生态农业建设的重要措施和技术手段。其实质是应用生态学原理，结合系统工程方法和现代技术手段，建立农业资源高效利用的生产方式和实施农业可持续发展的技术体系。作者在理论研究和多年实践的基础上，系统总结、介绍了当前我国农业生态工程10种主要的技术类型：充分利用空间和土地资源的农林立体结构生态系统；物质能量多层分级利用系统；水陆交换的物质循环生态系统；相互促进的生物物种共生生态系统；农-渔-禽水生生态系统；多功能的污水自净工程系统；山区综合开发的复合生态系统；沿海滩涂和荡滩资源开发利用的湿地生态系统；以庭院经济为主的院落生态系统；多功能的农副工联合生态系统。

The Major Technical Types of Agricultural Eco engineering in China

Agro ecological engineering is the significant content of eco farm construction and is the important measures and technical means for the implementation of eco farm construction.In substance,it applies principles of ecology and combines with system engineering methods and modern technical measures to establish the production mode for efficiently utilizing agricultural resources and implementing technical system of sustainable development in agriculture.This paper systematically summarizes the ten current technical types of agricultural eco engineering in China:the agricultural and forestry three dimensional structure eco system type for fully utilizing space and land resources;multi level and graded utilization of material energy;material circulatory eco system type of land and water exchange;bio species symbiotic eco system type for mutual promotion;agricultural fishing poultry aquatic eco system type;multi functional sewage self purification system;comprehensive development compound eco system in mountainous region;wetland eco system type for resources development and utilization in coastal beach and marsh;courtyard eco system type;and multi functional joint eco system type of agricultural,sideline production and industry.
