植被是重要的自然资源之一。一个地区植被的性质和特点,最能反映该地区的自然条件。只有摸清这一地区的植被资源、性质与特点,才能为该地区的农、林、牧区划和生产建设方针,以及植被的恢复提供重要的科学依据。本文通过对陕北黄土高原现存植被的研究与分析,为该地区的农、林、牧区划和生产建设方针,以及植被恢复方案,提供重要的启示。一、植被的类型本文所指陕北黄土高原,在地理位置上系铜川、韩城以北和长城沿线以南广大的黄土丘陵和高原沟壑区。位于北纬约35°10′～37°30′(东北角可至39°20′),东经107°20′～110°40′。
Vegetation is one of the important natural resources. The nature and characteristics of a region’s vegetation best reflect the natural conditions of the region. Only knowing the vegetation resources, nature and characteristics of this area can provide important scientific evidences for the policy of zoning, production and construction of agriculture, restoration of vegetation in this area. Through the research and analysis of the existing vegetation in the Loess Plateau of northern Shaanxi, this article provides important inspiration for the policy of zoning, production and construction of agriculture, forestry and pastoral areas and the plan of vegetation restoration in this area. First, the type of vegetation This refers to the northern Shaanxi Loess Plateau, in the geographical location of Tongchuan, north of Hancheng and along the Great Wall south of the vast loess hills and gully areas. Located at latitude 35 ° 10 ’~ 37 ° 30’ (northeast corner can reach 39 ° 20 ’), east longitude 107 ° 20’ ~ 110 ° 40 ’.
