摘要
为了解抚顺龙岗山省级自然保护区林木资源现状,本研究利用往期地形图(常规测量法)、航片(航空遥感法)、卫星遥感图片(卫星遥感调查)和3S综合调查法对区域内土地资源进行综合调查,结合卫星遥感影像及历年森林资源变档数据对区域内林分进行区划。结果表明:保护区总面积4550.61 hm^(2),保护区内有林地面积4408.17 hm^(2),总蓄积量为646354.00 m^(3)。有林地林龄结构齐全,其中以中龄林为主,其面积和蓄积量分别占保护区总面积和总蓄积量的39.81%和40.83%。保护区内森林的建群树种比较简单,针叶优势树种为落叶松,落叶阔叶优势树种为栎树。该结果可为更好地保护龙岗山省级自然保护区的原生性森林生态系统及生物多样性提供理论依据。
To understand the current situation of forest resources in Longgang Mountain Provincial Nature Reserve in Fushun,the previous topographic maps(conventional surveying method),aerial photos(aerial remote sensing method),satellite remote sensing images(satellite remote sensing survey)and 3S comprehensive survey methods were used to conduct the comprehensive survey of land resources in the region in this study.The satellite remote sensing images were combined with the data of forest resources over the years to divide the forest stand.The results showed that the total area of the nature reserve was 4550.61 hm^(2),the area of the forest land was 4408.17 hm^(2),and the stock volume was 646354.00 m^(3).The forest age structure of the forest land was complete.The half-mature forest was the main forest.Its area and stock volume accounted for 39.81%and 40.83%of the total area and stock volume respectively.The constructive tree species of forests in the nature reserve were relatively simple.The dominant coniferous tree species was mainly Larix gmelinii,and the dominant deciduous broad-leaved tree species was mainly oak.The results could provide a theoretical basis for better protecting the original forest ecosystem and biodiversity in Longgang Mountain Provincial Nature Reserve.
