分水岭防护林:石质山的梁岗分水岭,石多、土薄、水土流失严重,是产生径流的起点,应当营造分水岭防护林,用以涵养水源,固结和改良土壤。高山、远山的分水岭地带,可封山育林育草,也可在完成工程措施后全部造林或带状造林。树种应以灌木为主,实行乔灌结合,可选用油松、荆条、柠条、胡枝子和棉槐等,栽植成疏透结构的林带。丘陵、漫岗分水岭的立地条件较好,应以乔木为主,适当混交灌木。 Watershed Shelterbelt: Lianggang watershed, stony, thin soil and serious water and soil loss are the starting points for runoff. Rocky shelter forests should be created to conserve water, consolidate and improve the soil. Mountains, mountains and watershed watershed can seal hillsides afforestation grass, but also in the completion of engineering measures after all afforestation or belt afforestation. Tree species should be shrubs, the implementation of the combination of arborvitae, the choice of pine, Jing, Caragana, Lespedeza and cottonseed, planted into a dredging structure of the forest. Hilly, Man Kong watershed site conditions are better, should be dominated by trees, the appropriate mixed shrubs.
