基于3S技术的南瓮河国家级自然保护区植被地上生物量初步估计

Aboveground Biomass in Nanwenghe National Nature Reserve Based on 3S Technology

以黑龙江省南瓮河国家级自然保护区为研究对象,利用3S技术完成保护区内各地类的区划、判读,然后进行野外植被生物量实测工作。通过统计分析,得到研究区内植被地上生物量总量为1 284.96万t。保护区最大的景观格局为森林,面积占总面积的58%,生物量占到总量的92%;其次是草本沼泽。二者面积占总面积的95%,生物量占总生物量的98.85%,是保护区内主要的景观类型。

Taking Nanwenghe National Nature Reserve in Heilongjiang Province as research object,regionalization and interpretation of every category were completed in Nature Reserve by using 3Stechnology.Through statistical analysis,it obtains that the total aboveground biomass in the study area are 12 849 600 t.The largest landscape patterns in Nature Reserve is the forest,its area constitute 58% of the total area;its biomass constitute 92% of the total,followed by marshes.Both constitute 95% of the total area;biomass,which constitute 98.85% of the total biomass,is the main type of landscape in Nature Reserve.
