  landform stability
     directly influnce on urban construction-and urban landform stability in this paper, the author discusses the influence of geological structure, earthquake; hydrological and engineering geology conditions, and crustal movement on urban landforms. He also indicates that geological background conditions plays an important role in urban constuction and evaluating of urban landform stability.

Vegetation in the sand zone of the Baiinxile Livestock Farm ofXilingol Steppe Natural Reserve was investigated during 1985-1986.The paper describes the distribution and succession of vegetation in thesand zone. 1. Vegetation in the sand zone shows mosaic patterns of open for-ests-brushwood-steppe in its western part and of closed forests-brushwood-steppe in its eastern part. There exists a vegetation ecological series fr-om west to east as the elevation increases. The Principal Component Ana-lysis of the vegetation highlights the fact that it is the gradient of st-ability of sand dunes and the gradient of soil water content that controlthe distribution patterns of the plant communities in the sand zone; 2. Succession of primary vegetation in the sand zone is described.The successional stage coincides with the process of sand-dune fixation.The stability of plant communities is highly correlated to the stability ofsand dunes. As the soil water content and heat vary with the variationof topography, the succession of vegetation has the sunlight-slope sereand the shade-slope sere, the former developing towards forests and thelatter towards steppe. 3. As regards the use and conservation of vegetation resources inthe sand zone, 6 suggestions are put forward.

1985-1986年期间,作者调查了白音锡勒牧场沙地植被。本文具体分析沙地植被的空间分布和动态演替。1.沙地西段的植被呈疏林灌丛草原景观,沙地东段的植被则呈密林灌丛草原景观。由西向东随着海拔高度的上升形成一个植被生态系列。植被PCA分析的结果表明沙地基质稳定性梯度和沙地环境水分梯度是控制沙地植物群落空间分布格局的两个主要环境因素。2.描述了沙地原生植被演替的各个阶段。沙地植被演替阶段与沙地固定过程相一致,群落稳定性与沙地地貌稳定性相关。由于地形分异引起立地水热条件组合变化,植被演替系列分化为阴坡系列和阳坡系列,前者向森林化方向发展,后者则沿草原化方向发展。本文还就沙地植被资源的开发、利用和保护等方面提出6项建议。
