- Abstract:
-
Forest-grass strip-intercropping system is one of the main models of agroforestry on steep slopes in arid and semi-arid area of Loess Plateau in China.Based on assessment of ecological,social and economic benefits of forest-grass strip-intercropping system,this paper presented the review on structure and optimal allocation of forest-grass strip-intercropping system in semi-arid area of Loess Plateau.The authors put forward that,the suitable species are Robinia pseudoacacia,Pinus tabulae formis,and leguminous grass(Medicago sativa,Astragalus adsurgens,Melilotus officinalis etc.) in forest-grass strip-intercropping system in semi-arid area of Loess Plateau.And a formula to calculate appropriate density for forest in the Loess Area has been developed through analysis on the balance of water supply and water consumption.Based on the analysis of recent studies on forest-grass strip-intercropping system,some current problems and future suggestions have been given to the research on forest-grass strip-intercropping system in Loess area.The authors hope this review can provide some useful references to process the forest ecological project in Loess area.
