摘要林窗是森林生態系統中一種普遍存在的現象,無論是健康的系統還是已經受到過度干擾的系統,林窗作為森林生態系統發展的重要驅動力,影響著森林的物種組成、結構以及森林的演替方向。The ecological study of macrofauna was conducted on four typical sampling stations selected in the northern muddy bottom area of jiaozhou bay, estuary of dagu river, culturing and nearby area in hangdao in mar., jun., aug. and dec., 2002. abundance and biomass of macrofauna were investigated by quantitative study. the macrobenthic community structure and biodiversity were analyzed through multivariate statistic analysis
本研究分別在膠州灣北部軟底區、大沽河口、黃島養殖區及養殖區鄰域選取四個典型站位,於2002年3月、 6月、 8月和12月野外采樣,對大型底棲動物進行了定量研究,採用多元統計方法分析了群落結構和生物多樣性,探討了底棲生物群落與環境因子的關系;用豐度和生物量比較曲線法分析大型底棲生物群落對自然和人為擾動產生的響應。Abstract : wind tunnel experiments were carried out to investigate the influence of wind direction on the wind pressure of proximite buildings. mean and fluctuating pressure coefficients on a high building, at sixteen different wind incidences and with one and two interfering buildings, were measured in the tests. this paper presents the characteristics of wind pressure on the building, which varies with the incident wind angle and with the numbers of adjacent buildins. due to the variation of wind angle and the interference effects, the complex feature of pressure distributions can be found on the downstream building surfaces for building group arrangement at certain angle of wind attack. some area of the interfered building for such configuration, in comparison with one single building ' s, may undergo very strong positive or negative pressures
文摘:通過風洞實驗研究了風向對兩個和三個鄰近建築風壓分佈的影響特性.實驗結果給出了在不同風向角下,作用於受擾建築上的平均和脈動風壓系數.當受擾建築處于下游位置時,建築之間的干擾效應主要表現為遮擋影響,建築物上的總體風壓系數不是很大,但在建築物表面上有時會產生局部較大的負壓系數.另外,在某些風向角下由於受到上游分離氣流的影響,在下游建築的局部表面又會出現較大正壓.這些結果可供建築布置和結構設計時參考I setted up the physical modele and calculation - domain for the conviction heat transfer enchancement by the longitudinal vortex, and did the numerical value simulation for the chang of the velocity filed and temperature filed which influnced by lvg. at the same time, i studied the generation develepment of the longitudinal and its mechanism for the heat transfer enchancement. by the analycise of the result, i got the pricipium rule of how the size, ratio corner and distence of the lvg have influence on the generation and develepment of longitudinal vortex, and gave out the relative construct parameter scope
通過對phoenics軟體進行應用開發,本文建立了渦旋強化換熱的物理模型和計算域,對擾流元作用下的流動速度場和溫度場的變化進行了數值模擬,研究了縱向渦旋發生發展及其強化對流換熱的機理。初步得出了擾流元的有關結構參數如總體尺寸、寬高比、攻角、間距等因素對渦流發生發展的影響規律,並給出了有關結構參數的取值范圍。All kinds of natural and human factors, including climate, organism, landform, m other rock and material, and human disturbance, influenced the genesis and devel opment of soils in shunde ecological paradise, guangdong province
