黄土丘陵区解决农村“三料”短缺的模式──林草间作

Models for Solving Shortage of“Three Materials”in the Loess Hilly Areas──Intercropping Tree With Grass

该文由社会林业概念谈起，阐述了林草间作模式的生态经济特征，举例论证了林草间作模式在解决黄土丘陵区“三料”俱缺问题方面的意义，表明：林草间作技术在黄土丘陵区有良好的生产应用前景。同时，根据生产经营的侧重点，可将林草间作模式分为三类：以林为主式，以草为主式和林草均衡式。通过对存在问题的探讨，作者认为关于林草间作模式及经营管理等问题仍需要进一步研究。

Based on discussing the conception of social forestry, eco-economic characteristics of themodels of intercropping tree with grass were stated in this paper,and the significance of the modelsin aspect of solving the shortage of“three materials”in the loess hilly areas was illustrated.It wasshowed that there would be a good production prospect in intercropping tree with grass. Based onthe emphasis of production management, the models of intercropping tree with grass might be divid-ed into three types,the type of taking tree as the dominant factor,the type of taking grass as thedominant factor,and the type of balance of tree and grass.By approaching the existing problem,theauthor thinks that the further research for construction and management of the models will be nec-essary.
