干旱

We choose the arid land of northwestern China as our study area because of its extensive area, specific geographical location, dry climate, varied topography, vulnerable ecosystems and long-term human disturbance, as well as the existence of current conflicts between economic development and environmental protection. Based on the literature, we choose ten desert species with clear and relatively accurate geographical distribution ranges to model their distributions:Anabasis brevifolia, Atraphaxis frutescens, Calligonum mon-golicum, Ephedra przewalskii, Gymnocarpos przewalskii, Haloxylon ammodendron, Haloxylon persicum, Ka-lidium cuspidatum, Salsola laricifolia, and Sympegma regelii.

：选择面积广阔、地理位置特殊、气候干旱、地形地貌多样、生态系统脆弱以及人类活动长期干扰，而且目前面临着西部大开发和环境保护双重矛盾的西北干旱区作为研究区域，通过收集西北干旱区多种优势种和常见种的地理分布资料，选取10种分布范围相对明确、资料相对齐备的荒漠植物种：短叶假木贼、木蓼(A- traphaxis frutescens)、沙拐枣、膜果麻黄、裸果木、梭梭柴、白梭梭、尖叶盐爪爪、松叶猪毛菜(Salsola lar- icifolia)和合头草，定量分析其地理分布与气候因子的关系，并据此估测其潜在中心分布区和潜在最大分布范围，与实际分布范围进行比较。
