| 摘 要： | 运用1997年二类调查数据,借助二歧指示种分类(TW INSPAN)方法,在ArcInfo的支持下,采用统一网格样点采样法,对吉林省汪清林业局金沟岭林场的森林景观的分类与演替进行了研究。结果表明:TW INSPAN通过15次划分,把整个金沟岭森林划分为7种经营景观类型,演替阶段从低到高依次为:人工纯林景观、榆杂林景观、杨桦林景观、阔叶混交林景观、针阔混交林景观、云冷落针叶混交林景观、阔叶红松林景观。同时,也说明TW INSPAN不仅可以有效地进行景观分类,还能反映景观类型在某一时空的梯度关系。

| Abstract: | Based on class II investigation on forest resources of Jingoulin forest farm of Wangqing Forestry Bureau,Jilin Province in 1997,by using dot sampling of gridding,the forest landscape classification and succession were analyzed with the help of TWINSPAN(two-way indicators species analysis) and ArcInfo.The results showed that seven landscape types were made at the spatial scale of the study area after 15 times divided by TWINSPAN.The succession grades were planted pure forest landscape,Ulmus propinqua and Shaw forest landscape,B.platyphylla and P.ussuriensis forest landscape,broad-leaf mixed forest landscape,needle-broad mixed forest landscape,Spruce,Fir and Larch mixed forest landscpae,broad P.koraiens forest landscape. |
