First, select four kinds of main risks source from bigly celebrate the main risk in region source, namely the flood, drought, sand-dust weather and petroleum pollution accident, etc. According to the different a request for to habitat, study this 19 kinds of landscapes ecosystem type of the Regional induce for 7 kinds of ecosystems system: Then the marsh of bulrush, lakes and reservoirs , salt alkali wasteland, prairie, island form wood, farmland, town. The difference is proceeded by characteristic according to each type ecosystem to the analysis of four kinds of main risks source, including the certain risk all rate, delimiting the space distribute, analyzing the risk strength to the receptor etc. At proceed the revelation the different from endanger to analyze the inside, this text borrows ecosystem index number that this index sign to reflect primarily habitat the ecosystem meaning of the type of habitat the different from position, with weak an index number to show the destructibility of the habitat, from but compute each ecosystem that is lost by ecosystem system an index number.

首先，从大庆地区主要的风险源中遴选出四种主要的风险源，即洪涝、干旱、沙尘天气和石油污染等；依据不同生物类群对生境的要求，将本研究区域的19种景观生态类型归纳为7种生态系统：即芦苇沼泽、湖泡库渠、盐碱荒地、草甸草原、岛状林、农田、城镇；对四种主要风险源的进行分析，包括确定风险概率，划定空间分布，对风险受体的作用强度分析等；在进行暴露和危害分析中，本文主要借生态指数这一指标来反映不同生境类型的生态意义和地位，以脆弱度指数来体现不同生境的易损性，从而计算出各受体生态系统的生态损失度指数；由于各主要风险物质对风险受体的作用强度是不同的，对形成区域性生态风险的作用大小也有差异，因此本文采用层次分析法对主要生态风险物质进行综合评价，并把判断矩阵排序权值的合理计算问题归为—非线性化问题，并提出用基于遗传算法(GA[5])的层次分析模型进行权重分析；进行风险表征，即综合前面两个阶段的信息，对环境中风险的性质和强度以及风险评价过程中不确定性问题进行分析与描述，并划分出五级生态风险区；最后，根据划分的五级生态风险区的特征，分别提出针对各生态风险区的生态风险管理对策。

Many kinds of meteorological factors influence dewfall amount in steppe community.

多种气象因子共同影响草原群落凝露的凝露量，在所有因子中近地表凝露层的空气湿度与气温是影响凝露的基本因素，而其它因子则通过修饰这两个因子而起作用。

Because they do disafforestation, opening up grasslands, reclaiming field from the intertidal zone, finally cause seriously ecology losing balance and destroying, forest decrement, soil erosion serious, climate worsing, desert broadening the scope, drought and flood harm frequently appearing, all these makes whole ecology going to worse and ...

因毁林开荒、开垦草原、围垦滩涂，结果导致生态平衡失调和破坏，造成森林减少、水土流失严重、气候恶化、沙漠化扩大，洪旱灾害频发，使整个生态环境趋于恶化，最终影响到人类自身的生存。本文列举了巴州地区土地开发的现状，分析了土地开发对生态环境造成的影响，并提出了生态环境保护对策与建议。

"Disclimax:a climax community that has been disturbed by various influences, especially by human beings and domestic animals, such as a grassland community that has been altered to desert by overgrazing."

"人为顶极群落：受到多种力量侵扰的变极群落，尤其是人和家畜，如草原群落由于过度放牧而变成沙漠。"
