和田绿洲地下水特征及其对生态植被的影响分析

介绍了和田绿洲地理气候概况,研究了该地区地下水化学组成、地下水矿化度与各组分离子之间的关系及其随地下水埋深的变化规律,对其地下水的化学类型变化规律作了简单分析。并对和田绿洲生态植被状况与地下水水质和水位之间的关系进行了分析。结果表明:和田绿洲的地下水水质不会形成钠害,对野生生态也没有构成制约因素,但地下水水位的高低对野生生态的分布起着重要作用。在降水稀少,而蒸发强度极大的和田绿洲,在水资源开发过程中将地下水位维持在一定范围之内,对保持绿洲生态稳定和社会经济可持续发展,具有重要意义。

Groundwater characteristics and their effects on vegetation in Hotian oasis

The natural geography and climate situations of Hotian oasis are briefly introduced. The chemical components of groundwater are analyzed. The relationship between groundwater depth and all kinds of ions and mineralization degree, the regulation of all kinds of ions and mineralization degree change with the groundwater depth and the relationship between the oasis vegetation conditions and the groundwater depth and quality are (analyzed). The synthesis result shows that the groundwater quality can not result in Na-calamity and is not the limiting factor to wild ecological environment. But the result also shows that the groundwater depth has important effect to existence, adaptability and succession of the wild vegetation. In the Hotian oasis, the precipitation is very exiguous, and the evaporation is very heavy. How to keep the groundwater depth at a certain level has important significance to keep the oasis stabilization and the socio-economy sustainable development.
