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。

By analyzing soil quality of 4 kinds of land use types in Kalamay agriculture development area according to principal component analysis, we draw the conclusions: nature shrub tree land is affected little by mankind, a great deal of organic matter return to soil every year, and root system can improve soil physical quality, can absorb salt from soil, so the soil quality of nature shrub tree land is the best; the soil quality of farmland is better than the soil quality of manpower Tamarix Bulrush land, which may be reasoned that man make for soil quality by irrigation to exclude salt and fertilizing organic muck in the earlier oasis digging up period. Soil physical qualities of tree land get harden and worsen for flooding irrigation, furthermore climate in Kalamay is dry and rainless , the other irrigation is very long time after the former one, so soil get harden severity and result soil physical quality get worse and worse.
利用主成分分析法分析新疆克拉玛依农业开发区四种土地利用方式下的土壤质量,得出:天然灌木林地,受人为影响较小,每年有大量有机物质返还土壤,且天然灌木的根系可以很好的改良土壤的物理性质,同时所选天然灌木林灌木多是耐盐碱并且本身又具有吸收积累来自土壤的盐分,土壤质量最好;农田受到的人为影响最大,但农田综合得分却好于人工柽柳芦苇地综合得分,这可能是由于在开垦初期的绿洲农田,受到了人们灌水压盐及增施各种有机无机肥料等有利于土壤质量提高的措施所致;乔木林地,由于人们用大水漫灌的方式灌溉,致使林地土壤变得板结,土壤物理性质下降,加上克拉玛依地区气候干燥少雨,一次灌溉后较长时间后才有下一次灌溉,致使土壤理化性质恶化,土壤质量不高。

Four substances including 2-methyl ethyl acetoacetate and barley straw extract distilled from bulrush as well as cetyl trimethyl ammonium bromide and isothiazo lintone were used for the comparison experiment in inhibiting the growth of Microcystis aeruginosa in various phases. Result showed that inputting chemicals in the lag phase has better effect than in the log phase, and adding in lag phase can effectively inhibit the algae growth. Although feeding allelopathic substance at log phase can lead to certain restraining effect, it cannot result in the effective inhibition of algae growth, which can be well achieved by feeding CTAB and isothiazo lintone below 10mgl/L during log phase.
