中文摘要	[目的]通过调查分析不同植物群落土壤理化性质、土壤酶活性的空间分布,了解生境变化过程中植物群落与土壤变化特征,为塔里木盆地西南地区荒漠生态脆弱区植被的恢复和管护提供理论参考。[方法]以和田河上游垂直河岸带4种植物群落类型(Ⅰ-灰叶胡杨+ 多枝柽柳+ 芦苇+ 胀果甘草;Ⅱ-灰叶胡杨+ 胡杨+ 多枝柽柳+ 芦苇+ 胀果甘草;Ⅲ-黑果枸杞+ 盐穗木+ 芦苇+ 胀果甘草;Ⅳ-花花柴+ 芦苇+ 胀果甘草)土壤为研究对象,采用分层取样方法,分析比较不同植物群落土壤理化性质、土壤酶活性空间分布特征,揭示制约荒漠河岸植物群落生存发展的关键因子。[结果]表明:4种植物群落类型土壤含水率、全盐量、碱解氮垂直分布异质性较为明显。同一土层之间含水率、全盐量差异性显著(P <0.05),群落Ⅳ各层土壤含水率均为最低,而全盐量在群落Ⅰ中最低,群落Ⅲ最高。4种植物群落土壤均呈碱性,pH值介于8.40 8.89,而全磷波动范围在0.53 0.86 g·kg~(- 1)之间,两种指标在各植物群落之间均没有显著性差异(P <0.05)。有机质、全氮、脲酶在群落Ⅰ各土层均为最高,而过氧化氢酶、碱性磷酸酶活性在群落Ⅲ最高。[结论]土壤含水率、土壤密度权重系数较大,对外界环境变化比较敏感,可以作为评价该地区荒漠植被土壤肥力的首要指标。
英文摘要	In order to reveal the key factors restricting the existence and development of desert riparian vegetation, the soil physicochemical properties,soil enzyme activities and their spatial distribution characteristics of four kinds of plant communities in the vertical riparian zone of upstream of Hotan River were studied with stratified sampling. The types of plant communities are: (Ⅰ). Populus pruinosa Schrenk + Tamarix ramosissima Ledeb. + Phragmites communis Trin. Fund. Agrost. + Glycyrrhiza inflata Batalin; (Ⅱ). Populus pruinosa Schrenk + Populus euphratica Oliv. + T. ramosissima Ledeb. + Phragmites communis Trin. Fund. Agrost. + G. inflata Batalin; (Ⅲ). Lycium barbarum Murray + Halostachys caspica C. A. Mey. ex Schrenk + Phragmites communis Trin. Fund. Agrost. + G. inflata Batalin; (Ⅳ). Karelinia caspia (Pall.) Less + Phragmites communis Trin. Fund. Agrost. + G. inflata Batalin. The results showed that the vertical spatial heterogeneity of the soil moisture content,total salt content and available nitrogen were more obvious than the other determined indexes in the four plant communities. The differences of soil moisture content and total salt content were obviously significant in the same soil layer of the four plant communities (P < 0.05). The soil moisture content was the lowest in every soil layer of community Ⅳ, the total salt content was the lowest in every soil layer of communityⅠ,but the highest in community Ⅲ. The pH values ranged from 8.15 to 9.17 in the four plant communities,the total phosphorus content fluctuated from 0.53 g ·kg~(- 1) to 0.86 g·kg~(- 1),both the pH values and total phosphorus had not significant difference in the same soil layers of the four plant communities (P < 0.05). The soil organic matter, total nitrogen and the activities of invertase were the highest in five soil layers of communityⅠ. The activities of catalase and phosphatase were the highest in every soil layers of community Ⅲ. The bulk density and soil moisture content had a strong correlation with other measured indexes,they were sensitive to the change of external environment,and could be used to evaluate the soil quality as the preferred indicators in the upstream areas of Hotan River.
