摘要

本文依據林業的二類調查數據，結合數學模型，比較了遼寧東部不同土地類型落葉松人工林的高生長狀况，研究結果表明：Chapman-Richards function適合比較落葉松人工林高生長狀况，土地的ELT分類系統適合落葉松人工林的立地區劃，緩坡最適合落葉松人工林高生長，日本落葉松比長白落葉松高生長好，是更適合發展落葉松人工林的樹種。

This study compared the growth of 2 larch plantations located in different land types in eastern Liaoning Province, China based on forest inventory data and mathematical models. Results demonstrated that the Chapman-Richards function was the most suitable model for the study site. The ecological land type (ELT) classification system is an effective tool for larch plantation zoning. Gentle slopes, including ELT2 and ELT3, were the best sites for larch plantations. Larix kaempferi showed greater growth than did L. olgensis. This research also indicated that species selection, such as L. kaempferi, was a key for forest plantation establishment and future stand development. Thus, species and site selections are key components for consideration in forest management practices.
