寒冷高原黄土丘陵浅山区退耕还林模式及造林技术

Patterns of Returning Cropland to Forest and Afforestation Techniques in Shallow Loess Hill Areas of Cold Altiplano

针对寒冷高原的特点,在对青海省大通县浅山退耕还林区立地类型划分的基础上,提出了退耕还林与绿色生态产业建设相结合,退耕还林与土地合理利用相结合,退耕还林与提高农民经济效益相结合的发展思路。并依此为出发点,对浅山退耕还林区林种、树草种、综合治理模式进行了优化配置,提出了适合寒冷高原黄土丘陵浅山区的退耕还林模式及综合造林技术,为该地区及其类似地区退耕还林工程建设提供了技术基础。

On the basis of the characteristics of cold altiplano, and site type division of returning cropland to forest of the shallow loess hill areas in Datong County, Qinghai Province, the development thinking of returing cropland to forest and green ecology industry combination, returing cropland to forest and land rational use combination, and returing cropland to forest and raising farmer economy benefits combination were presented. According to the above, forest type, tree(grass) species and comprehensive control patterns were optimizedly collocated, and the patterns of returing cropland to forest and afforestation techniques in shallow loess hill areas of cold altiplano were found. This results could provide techniques foundation for this area and other similar areas.
