摘要
通过多年的引种对塔拉的生态适应性研究表明 ,极端低温及降水是制约塔拉生长发育的关键因素。据此将哀牢山以西、怒江、澜沧江下游海拔 145 0m以下 16个县的 12 8个乡镇区划为云南种植塔拉的最佳适生区 ;哀牢山以东、元江中下游海拔 12 5 0m以下 14个县的 81个乡镇为一般适生区 ;公益林种植区为金沙江中游海拔110 0m以下的 10个县的 6 2个乡镇。
Introduction for years and the research on the ecological adaptability of Caesalpinia spinosa in Yunnan indicated that the extreme lowest temperature and rainfall were the key factors affecting the growth and development of Caesalpinia spinosa One hundred and twenty eight towns and townships belong to 16 counties located at the west of Ailao Mountain, lower reaches of Nujiang River and Lancangjiang River with the elevation lower than 1 450 m, were divided as the optimum ecological region Eighty one towns and townships belong to 14 counties located at the east of Ailao Mountain, middle and lower reaches of Yuanjiang River with the elevation lower than 1 250 m, were divided as the passable ecological region Sixty two towns and townships belong to 10 counties located at the middle reaches of Jinshajiang River with the elevation lower than 1 100m were divided as public benefit forest planting area
