The observation on the growth of shell height and mortality of Pinctada martensi was carried out in Dongshan Pearl Oyster Mariculture Farm during the period from July, 1993 to December, 1994. This paper reports the growth of shell height, population structure, mortality and the differences among observed groups at different periods.The results are shown as following: 1. Increment in shell height: The trend for the growth of shell demonstrated that the highest growth rate occurred in small size shells or larva shells with height less than 40 mm,in which the height increment may be much as 25.0 to 32.8 mm. The growth rate was slowing down for middle size shells with heights of 40 to 50 mm, in which the increment ranged from 8.9 to 12.8 mm. The growth rate was lowest for adult shells with heights between 50 to 60 mm. Thus, the decreasing growth rate exihibits in the order of larva or small shells,middle size shells and adult shells. 2. Population structure: The shell heights tended to show the normal distribution for the early stage of population ( Fig. 1 ), during which 70% of individuals dominated thea same height. With the growth and death of individuals, the normal distribution comes to be vague or deformed. 3. Mortality: The mortality was lowest for the post-spat,then for early spat,middle size shells, adult shells and nucleared shells in sequence. The survival rate showed in the other way in order. The post-spats showed hightest survival rate of 29 4% and nucleared shells showed only 3 7%(Tab. 4). 4. There was no direct impact of warm water to the Pearl Farm. However, due to the inflow of great amount of silt from surounding waters, the depth of water at the farm is getting shallower. Besides, the factors such as living sewage due to population increase, entrophication resulting from shrimp pond discharge etc. may undoublely threaten the growth of Pinctada martensi. The environmemtal variations and the state of warm water covering areas resulting from the discharged warm water from the nuclear power station in Daya Bay are preliminarily described.

With transect sampling,effects of forest boundary forms on specie composition and its distribution and on growth and death of colonizing woody plants were measured at the birch forest tundra ecotone in Changbai Mountain,Northeastern China.The boundary microclimate relative to forest boundary forms,causes of colonizing patterns,and timberline dynamics were also studied. Betula ermanii and Alnus mandshurica predominated in the colonizing woody species on forest boundaries.In general,transects facing concave boundaries had higher values of colonizing distance and stems,mean base diameters,total base areas and average heights of colonizing stems than those next to convex and straight boundaries respectively.Those adjacent to convex boundaries presented minimum values and decreased abruptly with increase of distance from timberline.Dieback rate and branching number increased with increasing distance from forest boundaries.The dead colonizing stems in transects next to concave boundaries had a wider range of and higher averages of base diameter than those of the transects adjacent to straight and convex boundaries.The numbers of dead colonizing stems were high in transects next to concave boundaries and low in those of convex ones.The death peaks of colonizing stems were in accordance with those of living stems along the transects next to concave boundaries.Density dependent process may be the major cause of death.However,the dead stems were concentrated at the middle or tail parts of transects next to straight and convex boundaries.So the severe microclimate may be the cause of death.The forest boundary forms were originated from heterogeneity of micro topography.The comprehensive effects of ecological factors such as wind and snow distribution and the spatial combination of ecological flows produced the patterns of colonization in various boundary forms.Therefore,boundary form may exert powerful control of the patterns of tundra colonization.The timberline in Changbai Mountain has not reached its potential altitude.The “concave convex reversal”effect resulted by boundary forms may be one of the causes of birch timberline climbing.

采用样带调查法测定了长白山岳桦林缘形状对入侵苔原木本植物组成和分布、树木生长和死亡的影响 ,阐述了林缘形状形成与生境小气候的关系 ,探讨了不同形状林缘更新格局形成的原因和林线的动态。林缘入侵物种主要由岳桦和东北赤杨组成。凹型林缘外入侵树木向苔原侵展的距离和茎数 ,以及平均基径、基面积之和及平均高度均明显高于直线型和凸型林缘 ,其中凸型林缘的值最低 ,且随远离林缘降低最为迅速。随远离林缘入侵植株枯梢率增高 ,分枝数增多。凹型林缘外死亡植株具有较宽的径阶和较大径级 ,平均死亡植株数也最多 ,而凸型林缘则最低。凹型林缘死亡植株数的峰值与入侵植株数量的高峰区间吻合 ,密度制约可能是幼树死亡的主要原因 ;直线型和凸型林缘林缘植株死亡峰位于茎数较少的样带中部和尾部 ,环境的恶劣性可能是植株死亡的主要原因。林缘小地形异质性是产生林缘形状的根本原因 ,林缘形状引起的入侵格局的显著差异是风和积雪等生态因子和生态流在空间上重新组合的结果 ,林缘形状对木本植物向苔原侵展具有强有力的控制作用。长白山岳桦林线尚未达到应有的潜在高度 ,林缘形状引起的“凹凸逆转”的生态效应可能是岳桦林线上升的一种机制
