| 摘 要： | 根据目前森林碳贮量的流行计算方法和西双版纳州森林资源调查数据,以乡镇为尺度,估算了20世纪90年代中期西双版纳森林植被的碳密度、碳贮量,并探讨了它们的空间分布以及气候因素、人类活动对其形成格局的影响.结果表明,全州平均碳密度为51.13 t.hm-2.从不同林型来看,栎类的碳密度最高,平均值为67.90 t.hm-2,其次是热带林、桤木类和松类,介于54~35 t.hm-2之间.西双版纳森林植被碳贮量达64.10 Tg,其中栎类占71%,其次是热带林和经济林.全州碳密度分布表现为北部、东部较高,中部、西部及南部偏低的格局.森林植被碳密度与年降水量有正相关性,与年均温呈负相关性,人类活动也是影响本区碳密度的一个重要因素.

| Abstract: | The carbon storage and density of forest vegetation were estimated on a township scale of resolution in Xishuangbanna in late 1990s based on the data of forest resource inventory and the main methods of calculating carbon storage of forest.Meanwhile,its spatial distribution and the influences of the climatic factors and human activities on its forming pattern were also studied.The results showed that the area-weighted mean of carbon density in Xishuaqngbanna was 51.13 t·hm~(-2).Among all the forest types,Lithocarpus forest was the highest in carbon density (67.90 t·hm~(-2)),followed by Simao pine,Alnus and tropical forests(ranged from 35 to 54 t·hm~(-2)).The total carbon storage in Xishuangbanna was 64.10 Tg,of which 71% comed from the Lithocarpus forests,followed by the tropical forests and economic stands.The carbon storage distribution presented a trend that it was higher in north and east while it was lower in central,west and south.The carbon density was found to be positively correlated with mean annual precipitation and negatively correlated with mean annual air temperature.Also,the human activity was an important factor affecting the carbon density. |
