摘要
本文根据华北落叶松分布和生产力的变化规律，确定了其气候生态指标和效值。根据生态因子间相互作用规律原理，提出了分析与评价华北落叶松生态适应性的数量化指标体系，包括热量指数ＧＴＩ，水分指数ＧＭＩ，水热指数ＧＭＴＩ。这一指标体系能够定量评价华北落叶松的生态适应性。本文应用水热指数ＧＭＴＩ对其天然分布区生态适应性等级作了定量划分，结果与实际情况相符。
In this paper, according to principles of Prince Rupprencht's distribution and productivity,it's climatic ecological indices were determined. The quantiative index system wasestablished to analyze and evaluate the ecological adaptation of Larix Prince Rupprencht.It includes the Growth-Therm-Index (GTI), the Growth-Moisture-Index(GMI) and the Growth Moisture-Therm-Index (GMTI). GMTI was applied to classify the ecological adaptation of thenatural distribution area of Larix Prince Rupprenct and the result was supported by the observation.
