利息保障倍数 - The studies on flocculation parameters of high turbidity water are completed more integrally , including establishing the equation about the relationship between the covering ratio of flocculent on silt surface 6 and the surface area of silt particles s . the re - concentration law of thickener underflow is studies
建立了一定沉速下，泥沙固体颗粒表面覆盖率与泥沙颗粒表面积s间的函数关系式；较系统地完成了高浊度水絮凝参数的研究。研究了高浊度水沉淀池排泥的再浓缩规律。 - The reasonable model of exploiting and utilizing to the plant resources is put forward , which should be mainly protected . all kinds of communities are analyzed . the aubor ' s average height of karst evergreen - deciduous forest is 6 . 88m . theuper arbor ' s average height is 13 . 07m . the highest one reaches 25m . the community cover ratio is over 90 % , only few gaps existnatural convalescence forest is inferior to karst evergreen - deciduous forest in the restoration degree . there are a few tall arbor in the community . the height of alpine shrubs forest is 1 . 00 to 2 . 00m . there is no dominant species . the average height of karst shrubs forest is 0 . 97m . the rhus chinensi s , desmodium racemosum and golochidion pubrum are the dominant species
以观赏及绿化树种、用材树种和药用植物等归类对洛塔植物资源作出了评价，观赏植物主要有：玉趼、百合、绣球花等；用材树种有大叶榉、香果树、光灰楸等；药用植物有南方红豆杉、杜仲等，并提出了对植物资源以保护为主的合理开发利用模式。分析各类型植物群落的保护年龄，地质与土壤背景以及群落基本结构和特征，喀斯特常绿落叶林乔木层平均高度为6 . 88m ，上层乔木平均高13 . 07m ，最高可达25m ，群落郁蔽度达90以上。 - The middle and lower parts of woodland and grassland had higher soil water contents during rainy season , which resulted from smaller evapotranspiration and more infiltrated water with a lower gradient . however , upslope runoff infiltration was another reason for hillslope with a lower cover ratio , such as bare land
雨季林草地坡中下部土壤水分含量较高的原因，可能主要与其蒸散较小且坡度较缓导致入渗水量较多有关；但是对于植被覆盖度较低的坡地(如裸地) ，坡中下部土壤水分含量较高还与上方来水有较大的关系。 - ( 2 ) runoff - yielding time on grassland with a higher cover ratio primarily depended on initial water content , and their relationship might be described by a power function too . surface crust could easily take place on bare land , so its runoff - yielding time primarily depended on rainfall intensity , and their relationship might be described by a linear function
( 2 )植被覆盖度较高的荒草地，产流时间主要取决于初始含水量，两者的关系可用幂函数描述；裸地因降雨产生地表结皮，产流时间主要取决于降雨强度，两者的关系可用线性描述。
