The basal geomorphology structure of the Tidal-Basin System of the Tiaozini Sandbanks is watershed and tidal creek system. We analyses its formation, evolvement, geomorphology characters and development and discusses the main influence factors which is water, sediment and space. We divide the evolution phases which is formation phase, autumn phase and contabescence phase. In the end we confirms its main functions, which is discharging the folium water on the tidal flat of the Tidal-Basin in the end of the ebb-tide, transporting sediment to Tidal-Basin through tidal creek systems, confining the swing range of the dynamical axis of flood tide or ebb tide, balancing the dynamical status of the South and North. At the same time, we compare coastal tidal-basin and sandbanks tidal-basin on geomorphology characters, formation causes, style and so on.
条子泥潮盆—潮沟系统的基本地貌结构为分水滩脊和潮沟系统,本文分别对它们的形成与发育、地貌特点及动态变化进行了分析,并探讨了影响其发育的主要因素,即来水条件、来沙条件、空间条件,划定了其主要发育阶段,即形成期、成熟期、衰亡期;在上述分析的基础上确定了潮盆—潮沟系统的主要功能,即通过潮沟系统渲泄落潮后期滞留在其潮盆范围内的滩面薄层水、通过潮沟系向潮盆内部输入或输出泥沙、限制涨落潮动力主轴摆动范围、平衡南北两侧动力状态;同时针对岸滩潮盆—潮沟系统与沙洲潮盆—潮沟系统的地貌特征、成因类型等进行了对比分析。

However, considering the water resource's sustainable utilization and taking marketing system of water resource as an assistance to raise the utilization efficiency of water resource. Genially speaking, the government must distribute the water which is related tightly to our dairy life and ecology.

The result makes clear, 2 class give urban sewage plant on the molecular quantity interval that organic owner should center the dissolvability in water water in kDa, and the content of organic matter compares hydrophoby the element of content big; of organic matter measures hydrophily interval distributings different organic thing shows water to accept filter film flux and hold back rate having distinct effect, the organic matter under molecular quantity 2kDa causes accept filter film to appear water flux attenuation bigger, organic matter is held back rate is minor, the organic matter that amounts to 57.2%; element to measure 10 ~ 100kDa causes accept filter film to appear water flux attenuation gentlier, organic matter is held back rate is older however highest the organic matter that amounts to 73.8%; to kiss scanty sex to differ shows water to accept filter film flux and hold back rate having distinct effect, classics is right of velar surface obstruction determine, confirm cause film to appear water flux and the main material that hold back rate change to be hydrophoby material, and the change that hydrophily material causes is minor.
结果表明,城市污水厂二级出水水中的溶解性有机物主要集中在kDa的分子量区间上,且疏水性有机物的含量比亲水性有机物的含量大;分子量区间分布不同的有机物对纳滤膜透水通量和截留率有着不同的影响,分子量2kDa以下的有机物引起纳滤膜透水通量衰减较大,有机物截留率较小,达57.2%;分子量10~100kDa的有机物引起纳滤膜透水通量衰减较平缓,有机物截留率却较大最高达73.8%;亲疏性不同的有机物对纳滤膜透水通量和截留率有着不同的影响,经对膜表面阻力的测定,证实引起膜透水通量和截留率变化的主要物质为疏水性物质,而亲水性物质引起的变化较小。

Three main methods with lacustrine carbonates have been used to reconstruct the lake water palaeo-temperature at present. First, the technique of isotopic geological thermometer, since being put forward to reconstruct sea-water paleo-temperature, was subsequently introduced into lacustrine carbonate sediments for constructing lake-water based upon the function relationship between lake-water temperature and the oxygen isotopic compositions of lacustrine carbonate and lake-water. Second, paleo-temperature of the lake-water can be reconstructed by determining Mg/Ca values of the lacustrine ostracode shells. And third, paleo-temperature of the lake-water can be reconstructed based upon the statistic model between the oxygen isotopic composition of lacustrine carbonate and the Lake-water temperature by testing the modem hydrogeological parameters and some relevant isotopic data of the lake basin.
目前利用湖泊碳酸盐对湖泊古水温进行重建主要有三种方式,一是运用同位素地质温度计原理,利用水温与湖泊碳酸盐氧同位素值和湖水氧同位素值三者之间的函数关系,对湖泊古水温做定量研究;二是通过测定介壳[Mg(上标 2+)]/[Ca(上标 2+)]进而重建古水温;三是通过测定湖泊流域范围内现代水文气象参数及一些相关的同位素资料直接建立起湖泊自生碳酸盐氧同位素值与温度间的统计模型。

It proves that tree top leaves suffer from water stress and hydraulic limitation becomes greater with tree height.Water stress influence tree height growth in several aspects:firstly is the influence of exterior water condition,and community average tree height is positive with exterior water condition.Secondly, hydraulic limitation influences individual tree structure and function.Xeromorphic structure,Lower water potential and turgor pressure limit cell division and expansion,which restrict gas exchange and carbon assimilation capability.However,respiration consumption increases with the spread of tree crown.Shortage of nutrient limits carbon investigation on new leave growth and may ultimately limit tree growth.Thus,the main limitation of tree height is water.
水分对树高生长的限制首先是外在的水分状况,群落的总体高度随外界水分状况的变差而变矮;再就是水力限制对单株树木的结构和功能的影响,水势降低、膨压减小使细胞的分裂和扩展受限,旱生型结构加剧水力对气体交换能力的限制、使光合碳同化能力受到限制、而呼吸消耗却随着树木个体的增大而增大,制造营养物质不足、使得营养亏缺、造成投入新枝叶的营养受限,最终限制了树高继续增长。
