Hydrothermal indexes for the growth of pinus tabulaefrmis were set up with aridityand annual accumulated temperature (≥10℃). The relationship betweern hydrothermal indexand average annual biomass was advanced, and the quality degrees of geographical distributionsof P. tabulae formis were divided based on hydrothermal indexes.

应用干燥度和≥10℃的年积温,建立了油松生长的水热指数;提出了油松生长的水热指数与年平均生物量的关系;根据水热指数划分了油松地理分布区的质量等级。

According to the wide-ranging data on geographical distribution of Gordoniaacuminata, several indexes widely used for the study of vegetationedimate interaction wereapplied. These indexes induded Kira's warndh index and coldness index, Xu's humidityindex, Penman's formula, Thornthwaite's potential evapotranspiration and moisture index,Holdridge's life zone classification system index, and other single climate indexes.

According to the wide-ranging data on geographical distribution of Gordoniaacuminata, several indexes widely used for the study of vegetationedimate interaction wereapplied. These indexes induded Kira's warndh index and coldness index, Xu's humidityindex, Penman's formula, Thornthwaite's potential evapotranspiration and moisture index,Holdridge's life zone classification system index, and other single climate indexes. Therelationship between the distribution of G. acuminata and dimatic hydrothermal conditionhad been analysed, and the Kira's water-temperature indexes for the upper, lower andnorth lindts of the vertical distribution of G acuminata were discussed. The principalcomponent analysis showed that relative effects of climatic hydrothermal indexes on thedistribution of G acuminata were in the order thermal factor>precipitation factor>accumulated suhshine time>re1ative hunddity. The potential changes of G. acominatadistribution area under elevated CO2 concentration were predicted by .using Holdridge'sindex of life zone classification system and gas circulati0n model's conclusion.

在广泛收集四川大头茶(GordoniaacuminataChang)地理分布资料的基础上,利用目前国际上被认为是较好的几种研究植被-气候相互关系的指标和方法,包括Kira的温暖指数和寒冷指数,徐文铎的湿润指数,Penman的干燥度指标,Thornthwaite的潜在可能蒸散和水分指数,Holdridge生命地带分类系统指标,以及一些单一气候因子指标,综合研究了四川大头茶的地理分布与环境水热状况的关系,讨论了四川大头茶垂直分布的上限、下限以及北界Kira热量指标状况.主分量(PCA)分析表明,气候水热指标对四川大头茶地理分布影响作用的相对次序是热量因子、降水因子、日照时数、相对湿度.利用Holdridge生命地带分类系统指标预测了CO2浓度倍增条件下四川大头茶地理分布区的可能变化.
