The dissertatio n constructs the index system, introduces the coefficients of development, coordination, fairness, and the coefficient of sd, which is composed by the former three and can reflects the sd overall strength of watershed, brings forward the quantative criteria of in order that the research of wrcc is based on the good watershed ecology and environment, the dissertation, according to the ecological appropriate theory, builds the logarithm normal distribution model about the relation between the growth of natural vegetation and the depth of groundwater ; based on this relation model, proposes a quantitative method of ecological water requirement ( ewr ) of natural vegetation in arid area, which utilizes the results of rs technique and the spot testing data of vegetative physiology demand
針對流域特點建立了基於水資源的流域可持續發展評價指標體系,引入發展系數、協調系數、公平系數,以及由其構成的衡量水資源支撐社會可持續發展綜合水平與能力的可持續發展系數,提出了可持續發展的定量判別方法。為保證在良好生態的前提下進行水資源承載能力研究,論文根據生態適宜性理論,建立了乾旱區典型天然植物生長與主要環境因子的偏態單峰對數正態分佈模型。基於此關系模型,利用遙感技術成果以及植物生理需水的現場實驗數據,提出了乾旱區天然植被生態需水量計算方法。Meanwhile, the study also shows that the diversity of studied cave animals is inversely proportional to human population density and water quality ; and bio - diversity, to some extent, is proportional to soil fertility and amount of chemical fertilizer, but inversely when excessive ; the correlativity between bio - diversity and vegetation cover rate is not obvious, when ground vegetation is strongly interfered by human being ; the amount of diestrammena marmorata is proportional to the d iversity of plant, and inversely proportional to soil fertility, and in a way, to water quality ; and the correlativity between community and water quality and soil fertility, and between water quality and the amount of mosquito and fly, is not as good as expected. the author points out that diestrammena marmorata, bat, mosquito, fly, oreolalaxrhohostig metus ( or cudata ), and fish can be chosen as in
同時,研究還表明:調查洞穴的物種多樣性與人口密度、水質成負相關;在一定范圍內,物種多樣性與化肥施用量、土壤肥力成正相關,超過一定的值則成負相關;在人類對地表植被的高強度作用下,物種多樣性與植被覆蓋率的相關性不明顯;蚊蠅數量與土壤肥力基本上呈正相關;斑灶馬數量與植物種數呈正相關,斑灶馬數量與在一定水質范圍內與水質呈負相關,與土壤肥力呈負相關;群落數與水質和土壤肥力、蚊蠅數量與水質都不能表現較好的相關性;研究認為,可以選擇斑灶馬、蝙蝠、蚊蠅、紅點囊蟾(或有尾類) 、魚類等作為指示動物對洞穴環境進行監測。There is a strong relationship between the vegetation cover and stability of oasis ecosystem which is the key location of mankind production and existence in arid and semi - arid land. the change of vegetation cover in arid and semi - arid has very important influence on the oasis eco - system, as it is very sensitive to the environment changes to oasis direction or to desert direction that the fluctuating index of vegetation cover. the vegetation cover rate change great effect on realizing the characteristic
植被覆蓋度對于乾旱區人類生存和生產核心場所的綠洲穩定有著直接的關系,在乾旱區覆蓋度的變化對本已脆弱的綠洲生態系統有著重要的影響,是向綠洲化還是向荒漠化的方向發展,十分敏感於綠洲植被覆蓋度的指數,了解各類植被覆蓋度的特徵及演化規律,對認識乾旱區生態環境的現狀及發展趨勢,辨識引起環境變化的驅動力,有著重要的意義。3. making the synthetic analysis with models and methods of rs and gis, this thesis achieves the data collection and information extraction of the ecological function regionalization indicators system, form the research achievements fixed region ecology environment system shape form. and analysis the land cover, vegetation cover, soil erosion etc. with rs, gis tools
3 .採用遙感技術和地理信息系統技術的多種模型與方法綜合分析,實現生態功能區劃指標體系各指標因子的數據收集和信息提取,形成定量反映區域生態環境系統安全形狀的研究成果:並對土地覆蓋、植被覆蓋、水土流失等主要因子進行了遙感分析和gis空間分析。The applying rs vegetation indexes in monitoring agricultural environment
