An ecological dominance was measured of plant communities after the forest fire onAmur of Mt,Daxinganling, by means of Simpson Index. By comparing them with thepermafrost environment, we conclude that the ecological dominanee is positively corelatedwith the degree of permafrost growth, and negatively corelated with the species diversity. Fur-ther more, we point out that there are two opposite effects from permafrost on the growth ofLarch forest,directly strong enforcement and indirect protection...

An ecological dominance was measured of plant communities after the forest fire onAmur of Mt,Daxinganling, by means of Simpson Index. By comparing them with thepermafrost environment, we conclude that the ecological dominanee is positively corelatedwith the degree of permafrost growth, and negatively corelated with the species diversity. Fur-ther more, we point out that there are two opposite effects from permafrost on the growth ofLarch forest,directly strong enforcement and indirect protection of the biological competi-tion. The forest responses accordingly under such environment, and also there are two oppo-site responses to the disturbances. Therefore in our practice of forest management,we cantake advantage of the positive effect of disturbances to reduce the enforcement on permafrostenvironment,and promote the forest growth.

本文以Simpson指数,测定了大兴安岭阿木尔林区火灾后植物群落的生态优势度。通过与冻土环境的比较分析得出,植物群落的生态优势度与多年冻土的发育程度之间呈正相关、与物种多样性之间呈负相关。并进而提出,多年冻土对该区兴安落叶松林的生长具有直接的高胁迫作用和间接的保护其生物竞争力的双重作用;森林植被则在此高环境压力下采取耐胁迫对策,对干扰也产生双重的响应方式。依此可指导我们在营林实践中有效地利用干扰的正效应而减轻森林的冻土环境压力,促进森林的生长和持续的利用。

This paper summarizes the applications of ground probing radar(GPR)to geologicalinvestigation on ground in cold regions such as delineation of massive ground ice underlying,detection of structure of permafrost,thickness measurment of rivers and lake ice,surveingand monitoring frozen earth containment dams and conditions around buried pipelines.

There are many phenomena demonstrating a commom degeneration such as buried frozen soil, pseudo-permafrost landforms variations of patchy permafrost table,multigelation, and vegetation changing in different regions.

The zoning boundaries of permafrost are theoretically determined from the relation between permafrost and modern climate in this paper. The boundary elevations are given in a profile. There are many phenomena demonstrating a commom degeneration such as buried frozen soil, pseudo-permafrost landforms variations of patchy permafrost table,multigelation, and vegetation changing in different regions. The important conclusion is that a basic trend of the permafrost changing in the plateau is degeneration.

本文从冻土与现代气候关系出发,理论上确定了冻土分区的界限。用剖面图展示出本区不同类型冻土分布的代表性高程,并以丰富的资料分析了出露在不同冻土区内的埋藏冻土层、冻土地貌假像、岛状冻土上限的起伏以及融冻地貌、植被变化等诸多现象呈现退化的一致性,得出了“退化是本区多年冻土变化的基本趋势”这一结论。
