【摘要】：我国分布着大面积的沙漠、戈壁,由于受到苛刻的自然条件影响,这些区域自然资源分类、数量与分布状况还不够清楚。针对这些问题,本文采用实地调查与资料收集的方法,根据沙漠戈壁自然资源的特殊性,建立了基于沙漠戈壁生态系统物理过程为主体的自然资源分类体系,并结合自然资源属性、可再生性和恒定性以及资源表现形式等指标,提出了资源群、资源类、资源型以及资源项4个沙漠戈壁自然资源分类的单位。采用上述分类理论体系和分类指标和单位,把沙漠、戈壁地区的自然资源分成2大资源群、3大资源类、9个资源型和22个资源项。并给出了22个不同自然资源类型的主要评价指标。同时,针对这些区域特殊而优势的自然资源,如太阳能、风能、生物资源和矿产资源的组成特点进行了分析。在这些结果的基础上给出了沙漠与戈壁地区自然资源利用与保护的对策。
[Abstract]:Because of the harsh natural conditions, the classification, quantity and distribution of natural resources in these regions are not clear enough. According to the particularity of desert Gobi natural resources, the classification system of natural resources based on the physical process of desert Gobi ecosystem is established by the method of field investigation and data collection. Combined with natural resource attributes, reproducibility and constancy, and resource representation, four units of natural resources classification in desert Gobi are proposed, such as resource group, resource class, resource type and resource item. The natural resources in desert and Gobi region are divided into 2 groups, 3 categories, 9 types and 22 resource items by using the above classification theory system, classification index and unit, and the natural resources of desert and Gobi region are divided into 2 groups, 3 kinds of resources, 9 types of resources and 22 items of resources. The main evaluation indexes of 22 different types of natural resources are given. At the same time, the characteristics of these special and advantageous natural resources, such as solar, wind, biological and mineral resources, are analyzed. On the basis of these results, the countermeasures for the utilization and protection of natural resources in desert and Gobi region are given.
