摘要: 基于全国380块样地资料,从宏观上阐明了油松林生物生产力的分布格局,建立了联系叶面积指数分布规律和地植物学知识的生产力水热相关模型与地理分布模型。在油松正常分布范围内(年均气温2~14℃,年降水量400/300~700/900mm),林分叶面积指数随年均气温的变化呈指数递减的函数关系,这是油松林适应水分协迫环境的一种机制。

Abstract: Based on the data from 380 plots over China, the productivity distribution patterns of Pinus tabulaeformis forest are indicated in large scale. Combined with the knowledge of leaf area index distribution and plant geography, the mathematical models for the relations of the productivity to the hydrothermal and geographical factors are established. Within the normal range of P. tabulaeformis distribution (annual mean temperature 2~14℃, annual precipitation 400/300mm~700/900mm), the leaf area index was exponentially and negatively related to the annual mean temperature, which may be a mechanism for the water stress adaptation of P. tabulaeformis forest.
