中文摘要	为了探索在盐碱地荒漠化防治中植物对水分变化的响应机理,提取黑河流域中游荒漠区建立的试验站长期定位监测的生物量、盖度、土壤各层质量含水率、地下水埋深、降水量等数据,采用特征参数算法、相关和多元回归分析方法,研究植物生长和水分的年内、年际变化特征及相关回归模型。结果表明,(1)2006─2014年,盖度、生物量、地下水埋深呈波动性增加趋势,0~10、10~20、20~40、40~60 cm土壤质量含水率和降水量呈波动性略有减少趋势。(2)在一年植物生长季的3─11月份,降水量、地下水埋深、土壤各层含水率、生物量和盖度等指标变化趋势基本一致。(3)建立了盖度与生物量、10~60cm(10~20、20~40、40~60 cm)土壤质量含水率、降水量、地下水埋深的回归模型以及生物量与盖度、10~60cm(10~20、20~40、40~60 cm)土壤质量含水率、降水量、地下水埋深的回归模型,且均通过了R~2拟合检验、F方差检验、t偏回归系数检验。建立的模型可以解释植物盖度、生物量的变差分别为95.3%、98.6%。该研究可为盐碱地荒漠化防治的水资源管理以及退耕还林、天然林保护等提供理论支撑和参考数据。
英文摘要	In order to explore response natural desert plant growth to changes of water in desertification of saling and alkaline control, extracted of establish long-term monitoring data about soil moisture content of each layer, vegetation biomass, coverage, groundwater depth and rainfall, which had come from test station of desertification of saling and alkaline control in Hongshawo had been set up in desert area in Heihe middle reaches, and the algorithm of characteristic parameters, correlation and multiple regression analysis method had been used, and response characteristics of natural desert plant growth and changes of water interannual and annual variance had been studied. Results show that:(1) The coverage, biomass and groundwater depth showed a trend of volatility increase, but the average moisture content of soil depth from 0 cm to 10 cm, from 10 cm to 20 cm, from 20 cm to 40 cm, from 40 cm to 60 cm and precipitation showed a trend of slightly volatility decrease from 2006 year to 2014 year in the research area. (2) In the growing season from March to November, the variance pace of each layer soil moisture content, coverage and biomass, precipitation and groundwater depth all were resemblance. (3) The regression model of coverage and regression model of biomass had been passed by R~2 test, F test and t test, and it was applicable and expandable. Through model analysis, the regression model of coverage could explain 95.3% variation of the coverage, and the regression model of biomass could explain 98.6% variation of biomass. This study could provide technology support and reference data for water resource management and evaluation of influence of water resource by engineering of returning farmland to forest, natural forest protection, comprehensive treatment of Heihe basin in desertification of saling and alkaline control.
