摘要: 黄土丘陵沟壑区是我国农业发展战略研究重点地区之一,也是我国水土流失最严重地区。其生态失调造成的恶性循环,使本区自然环境恶化,土地生产力衰竭。本文拟从延安市附近土地类型研究入手,揭示黄土丘陵沟壑区土地类型结构格局、分布规律、阐明土地类型的自然特征、演替图式及改造利用措施,为合理利用土地资源、合理布局农林牧业生产,进行生产规划提供科学依据。

Abstract: In the paper,taking Yan An nearby regions as a example, the land types of loess hills and gully areas of northern Shanxi province are discussed. Loess hills and gully areas are an important region for developing agriculture.The loss of water and erosion of Soil are severe, in the region. Based upon specific natural condition of Yah An nearby region, some Principles for classifying land types are given.According to these principles,taking landform, vegetation and soil as chief criteria for classifying land types, 5 land types of first category and 23 land types of second category are identified in Yah An nearby regions.A hierarchical scheme for land classification in the region is introduced. Horizontal and vertical structure,and developing diagram of land types as well as the physical features of main land types are discussed.In addition,an approach to the direction of production-construction in the hills and gully areas of northern Shanxi province is also made in the paper.
