夏玛保护站地处甘肃省天况藏族自治县东北部,其所辖的夏玛林区水源涵养林在河西地区经济社会发展中起着重要作用。由于历史上的乱砍滥伐、毁林垦荒、过度放牧、战火侵袭以及无节制的樵采,林区森林遭受严重破坏,形成了一定数量的残林迹地、疏林地和灌丛林地,森林的综合效能下降。从20世纪50年代开始,林区采取了一系列封山育林措施,几十年的实践证明,封山育林是恢复森林植被的一种有效途径,可以使森林资源得到一定恢复和发展,使森林的生态、社会和经济效益得到提高。科学确定封育方式、调查内容、研究方法夏玛保护站的封山育林区总面积1097公顷,主要包括残 Xiama Protection Station is located in the northeastern tibetan Autonomous County of Gansu Province, under its jurisdiction Shamaolin water conservation forest in Hexi area economic and social development plays an important role. Due to the deforestation, land reclamation, overgrazing, war infiltration and incurable firewood in the history, the forests in the forest area have been seriously damaged, forming a certain number of residual forest land, sparse forests and thickets, forest Overall efficiency decreased. Since the 1950s, a series of measures have been adopted to forest cover forests in the forested areas. Decades of practice have proved that closing the mountain and afforesting forests is an effective way to restore forest vegetation so that forest resources can be restored and developed to make the ecology and society of forests And economic benefits have been raised. Science to determine the sealing method, investigation content, research methods Shama protection station closing hillsides afforestation area a total area of ​​1097 hectares, mainly including residual
