扎龙国家级自然保护区土地利用调查与分析

Investigation and analysis of soil utilization in Zhalong National Natural Protection Area

根据扎龙国家级自然保护区划界和功能区区划,利用1986—2002年不同代表时段的卫片,通过土地利用时间、空间变化模式和利用程度、质量变化模式,分析了保护区土地利用的类型、结构和程度的变化过程,提出了维持湿地功能的主要土地类型湖库、明水沼泽、芦苇沼泽的基本控制面积.为保护区湿地的管理以及相关研究工作的开展提供了科学的依据.

The status in quo of the soil utilization is analyzed using photos taken by the secondary planet from 1986 to 2002 in Zhalong National Natural Protection Area, which is based on the delimitation and function compartmentalization of the area. The resulted information gives the exacted areas of the important kinds of soil types, such as lakes, heavy swamp, and reed swamp, to sustain the basic functional demand of the wetland area. It is also hoped that this investigation is helpful to supply the scientific data for the management and scientific research of Zhalong wetland.
