本文阐述了农林业系统工程概念,简要介绍了国外的发展现状与趋势,重点介绍了我国农桐间作的结构模式。
The author regards it convenient to use the term 'AgroforestrySystematic Engineering' to represent the practice of agroforestry in China.After a detailed introduction of intercropping practice of Paulownia andcrops in China, which is the major form of systematic engineering of agr-oforestry, the author indicates that from the point of view of ecology, Paulo-wnia and crops have no antagonistic contradiction with regards to utilizationof light energy and to water/fertilizer supply. There are three categoriesof intercropping of Paulownia and crops, i. e. the intercropping with agr-iculture as the dominant factor, or with Paulownia as the major factor,or,a simultaneous development of Paulownia and crops. In formulating theintensive cultivation techniques and management measures, it should beemphasized to plant proper tree species in appropriate location, to disposethe crops reasonably, to select strong sprout (the standard of strong spr-out) and to choose the right crop variety and the right Paulownia variety.The author also suggests to strengthen the theoretical research o f agrof-orestry systematic engineering, and to establish stable ecological observa-tion stations of Paulownia/crop over the agricultural areas of the HuangHuai Hai plains. It should also be encouraged to carry out biomass andproductivity research. Paulownia and crop variety development by selectionshould be continued. The research on intensive cultivation technique forshort cycle felling, and the research on Paulownia-wood processing andits synthetic utilization should also be carried out. The paper gives a shortintroduction o f overseas present development state abd its trend.
