滩地

于同年4月和11月分别用GPS法对有螺滩地进行定位随机抽样调查钉螺。

Snail survey was conducted in April and November respectively in the area located by GPS .

土壤pH值在滩地和固定沙丘的空间分布符合球状模型且空间自相关显著，但在半固定沙丘空间自相关不显著；

The soil pH did not exhibit significant autocorrelation in the semi - fixed sand dune but it did significant autocorrelation in the meadow and the fixed sand dune , both fitting the spherical model .

结果表明：1m范围的高程差影响植物种类组成，其趋势表明滩地1m的高程差已构成水分环境的变化；

The results showed that 1 metre difference for elevation of beach land would influence its species composition since the water condition was changed .

滩地造林使原优势种芦苇（Phragmitesaustralis）和荻（Miscanthussacchariftorus）的重要值和生物量都有所下降；

Afforestation on beach land leaded to IV and biomass of dominant species ( Phragmites australis and Miscanthus sacchariftorus ) decreased in the herb community .

以Forman提出的集中与分散相结合的景观格局理论重构郑州黄河滩地景观结构。

Landscape structure of the Zhengzhou Yellow River Floodplain was reconstructed by using " the centralism and the dispersed phase unify " the landscape pattern theory Advanced by Forman .

现场实验：浸泡法、滩地喷洒法的样品组和对照组72h后钉螺死亡率分别为95.9%、93.3%和100%、95.8%；

In the field , the snails death rate in sample group and in contrastive group applied with immersing method and insufflation method for 72 hours were 95 . 9 % , 93 . 3 % and 100 % , 95 . 8 % ;

计算4块滩地的中位数、95%可信区间（95%CI）等描述性统计指标，并分别用负二项分布、对数正态分布、指数分布和Weibull分布拟合钉螺数据以分析钉螺的分布规律。

The corresponding descriptive statistical indices of the snails including median , 95 % confidence interval ( 95 % CI ) and aggregation index were calculated . Finally , the negative binomial distribution , log-normal distribution , exponential distribution and Weibull distribution were fitted to the data of Oncomelania hupensis .

按EPD公式推算，宿主每天排出的有效虫卵数牛占99.6%，人仅占0.4%，滩地实际污染结果与推算基本相符。

Being calculated according to the formula of EPD , effective egg number in cattle accounted for 99.6 % . among total egg . discharged by hosts , but 0.4 % in human only , the realistic pullution accorded basically with the result calculated .

寒冻雏形土不同地形部位0cm～50cm层次地温均表现较低的水平，且南坡>滩地>北坡。

The ground temperature is low at the depth of ? 0 ~ 50cm in the different topographic area of the Mat Cryic Cambisols , and southern slope fields > valley plain > northern slope fields .

为同类型山区多泥沙河流滩地开发和保护提供借鉴。

It provides reference for the same kind of mountain area .
