天然植被

从植物生理角度分析生态需水，得到天然植被的总腾发量Et，作为植被生态需水总量。

The total evapo-transpiration ( Et ) of natural vegetation is obtained by the analysis of the plant physiological conditions , which is taken as the vegetation ecological water demand .

利用Clements多度记录法调查确定了天然植被中群落的优势种和建群种。

Clements'abundance documentation approach was employed to determined the dominants or edificators of the natural vegetation .

各典型天然植被的Et通过实验资料获得。

The typical natural plant Et can be obtained by experimental data .

天然植被覆盖变化敏感区间为5～8m；完全衰败现象出现于超过10m的降幅范围内；

The sensitive region is in 5 m - 8m and the severe decline area over 10 m ;

本文以RS、GIS为技术平台，综合运用地统计学、生态水文学的理论基础，重点分析了干旱区地下水位降幅对天然植被退化过程的影响。

In this dissertation , by using RS , GIS technology , synthesizing theory of Geostatistics and ecology hydrology , the effects of the depth downrange of groundwater on nature vegetation degeneration in arid area are analyzed .

地下水位降幅在0～5m之间，天然植被覆盖变化不大；天然植被覆盖变化敏感区域居于5~8m降幅之内，超过10m降幅将出现严重退化区；

In the typical study region , change area of nature vegetation is not obvious in 0 m-5m ; ( 2 ) there were the sensitive region in 5 ~ 8 m and severe decline area over 10 m ;

红鳞蒲桃（Syzygiumhancei）是广西滨海生态过渡带天然植被的重要组成树种，在北部湾生态环境建设中具有重要的作用。

Syzygium hancei is a important tree species of natural vegetation in coastal ecotone of Guangxi , which plays an important role to the ecology environment construction of Beibu gulf .

本文针对本地区关于GSPAC系统水分研究较少，在试验区选择2种主要天然植被进行了观测试验；

Under this background , this article has carried on the observation experiment to two kinds of main natural vegetation in experiment plot .

同时，研究结果表明，截止2002年9月，在塔里木河下游中段，生态输水对地下水影响范围为800m，天然植被恢复的范围为700m。

By the end of September 2002 , the result showed that the respond range of the ground water level was 800m from the river , and the respond range of vegetation was not beyond 700m at the middle part of lower reaches of Tarim River .
