摘要

通过野外调查花花柴（Karelinia caspica）植株及其沙堆形态指标，应用统计学原理和方法，分析了绿洲-沙漠过渡带花花柴沙堆的形态特征及沙堆与植株形态间的关系，初步估算了花花柴植株可固定的。结果表明:(1)花花柴沙堆形态依据其发育时期的不同主要分为早期的盾形沙堆和较稳定时期的半球形沙堆。盾形沙堆的长度与宽度、底面积与高度间均呈直线线性相关，半球形沙堆则呈二次线性相关。盾形沙堆在向半球形沙堆发育的过程中，沙堆长度缩短，但是其高度、宽度以及体积仍随着沙量植物的生长而不断地增长。(2)沙堆的发育与植株的形态有显著的相关关系。早期发育的盾形沙堆长度约为植株长度的2倍，体积为植株体积的1.5倍，半球状沙堆的长度和体积均约为植株的0.5倍左右。(3)通过估算，在策勒绿洲-沙漠过渡带上，花花柴草丛沙堆体积可达约50 000 m3·km-2，表明花花柴沙堆截留了绿洲外围大量的流沙，是绿洲的重要屏障。

Abstract

Based on observed data of carelinia caspica and carelinia caspica nebkhas and statistical methods, we analyzed morphological characteristic carelinia caspica nebkhas and the relation between the nebkhas and the plant morphology, and estimated the quality of sand fixed by plants at the oasis-desert ecotone of Cele, Xinjiang of China. The results are as follows. (1) Carelinia caspica Nebkhas can be mainly categorized into shield-shaped nebkhas at early developing stages and hemispherical nebkhas at stable developing stages according to different development periods. There is a linear correlation between length and width of shield-shaped nebkhas, and so do the basal area and height, but there is a quadric linear correlation for hemispherical nebkhas. During the development process from shield-shaped nebkhas to hemispherical nebkhas, the length of the nebkhas decreases, but the height, width and volume of nebkhas increases as plants grows. (2) There is a significant correlation between the development of nebkhas and the form of plants. The length of shield-shaped nebkhas is twice as long as that of plants, and the volume of shield-shaped nebkhas is 1.5 times as large as that of plants. The length and volume of hemispherical nebkhas are 0.5 times as large as those of plants. (3) It is estimated that the volume of Carelinia caspica nebkhas can be 50 000 m3 per km2 at the oasis-desert ecotone, which indicates that Carelinia caspica nebkhas fix a great deal of sand surrounding the oasis and plays an important role in oasis protection.

Key words： Carelinia caspica nebkhas; morphological characteristic; sand-fixation capacity; oasis-desert ecotone; Cele
