摘要
以生态适宜性理论为基础,根据塔里木河干流流域典型植物的随机抽样调查资料,建立了干旱区几种典型植物生长与地下水位关系的对数正态分布模型。根据建立的模型得出干旱区典型植物的最适地下水位、适宜地下水位区间及其对环境因子的忍耐度。与同是干旱区的黑河流域下游额济纳旗实测及调查资料进行比较分析,结果是合理的,因此模型也是合理的。最后,根据模型得出了对干旱区生态恢复和重建,实现干旱区经济、社会和生态环境协调可持续发展具有重要意义的结论和建议。
According to the ecological appropriate theory and the random sampling investigation date of several major plants in the Tarim basin, the logarithm normal distribution relation model between the growth of plants and the depth of groundwater was built. Based on the model, the fittest depth and suitable range of groundwater of these plants and their tolerance towards groundwater are gained. Compared with the measure and investigation data in other arid area, i.e. Ejin Banner in the lower Heihe basin, the result and the model built above are rational. Lastly, the conclusion and rational suggestion are proposed, which may be important for ecology construction and resumption and for sustainable development of arid areas.
