The crystallization temperature and pressure of clinopyroxene phenocrysts from the ankaramite and basalt were estimated on the basis of the clinopyroxene-melt equilibrium principle: 1345~1366℃ and 1.75~2.05Gpa for ankaramite, with average geothermal gradient of 20-24℃/km, suggesting anomalous heat or geothermal gradient in this region may be one of the key reasons to produce the porphyry copper deposits in the region. In contrast, those in the basalts fomed under a relatively low crystallization temperature (1129~1191℃), and the pressure (1.19~1.60Gpa) and depth (39~53km), suggesting that the basalt formed under a condition of lower temperature and pressure.
根据单斜辉石-熔体平衡原理计算了富辉橄玄岩和玄武岩中斑晶相辉石形成的温度和压力,前者变化范围主要集中在1345~1366℃和1.75~2.05GPa,其深度相当于58-67km,平均的地温梯度大约20~24℃/km,说明该区具有异常的热或地温梯度,这可能是导致本区斑岩铜矿形成的主要原因之一;后者的温度和压力都相对较低,分别为1129~1191℃和1.19~1.60Gpa,而相应的深度为39~53km,暗示着玄武岩是在相对低温低压的环境中形成的演化岩浆。

The temperature of cold injury was abo ut 0 ℃ to 15℃,While hot injury would appear when temperature got to 36℃.These ind icat ors were varied in different species,and the greatest difference was the temper ature of cold injury.Growth would be poor in summer under full illumination,whi le part shading was beneficial.The best condition was 70 percentage of sh ading for Araceae and 50 percentage of shading for Agavaceae.The need for soil moistu re was strict.Most of species would grow normally in 65 to 85 percentage of soil m o isture.The characters responsed to illumination,temperature and soil moisture w e re consistent with their original ecologic environment.
其最 适生长温度在16-35℃,除酒瓶兰外,低于10℃时均表现生长停滞状态;寒害温度差异很大,天南星科为0-15℃,龙舌兰科为0-10℃,大多数植物在36℃会产生热害;光照对其影响较大,夏季这两科植物在全光照下长势差而在一定荫蔽的条件下有利生长,最佳荫蔽度天南星科为75%,龙舌兰科为50%;这两科植物对土壤中的水分含量要求较高,大多在土壤含水量70%以上才能正常生长,这些光、温、湿的反应特性与其起源地湿热和荫蔽的生态环境相吻合。

This suggests that the effects of temperature on growth of the two coral species were different. Growth rates of S. hystrix at 25℃ were stable and higher than those of S. pistillata. However, the effects of temperature on growth rate of S. hystrix may be modified by other factors (e.g., mesocosm effect) in higher or lower temperatures. The mortality of S. pistillata in three temperature treatments was very low, while the partial mortality of S.
