隆回县高海拔山区高效生态经济型退耕还林造林模式研究

通过对六种植物配置方式及三种开发模式的对比试验分析，试验出了一种融水土保持效益与经济效益于一体的高效生态经济型造林模式，并探讨了灰毡毛忍冬产量与海拔高度的关系．结果表明：在自然条件恶劣的小沙江高海拔山区，采用金银花(品种为灰毡毛忍冬) 三木药材或其它草本药材，运用景观生态学原理进行设计开发，可获得很好的经济效益与社会效益，并能保持山区的可持续发展．同时还试验出了主栽树种灰毡毛忍冬在海拔1000～1400m之间时经济效益最好．

Studies on high efficient and eco- economic afforesting model of the Cropland Conversion to Forest/Grassland at high- elevation mountain area in Longhui county

High efficient and eco - economic model in which soil and water conservation and economic benefits were existed was studied, and the relationship between the yield of lime panniform honeysuckle and elevation was probed in to by comparing and analyzing setup style of six plants and three development styles. The results showed that high economic and social benefits were gained, sustainable ways of main variety (lime panniform honeysuckle)which growed at the elevation of 1000 to 1400 metres was the highest by designing and developing honeysuckle, three tree(medicinal materials)or other herbal medicinal materials by adopting landscape - ecology principle at small sand river mountain area where natural conditions were bad and the elevation was high.
