摘要
结合那曲市色尼区光照、温度、大风、土壤等自然环境因子,探讨植物在那曲高寒高海拔地区恶劣环境条件下的光合作用特征、环境限制因子,造成植物生长季积温不足、生长期短,加之全年多发大风和晌午强光辐射等环境因素共同作用,导致城镇绿化植物光合效率低下、光合产物少,从而致使植物抵抗那曲高寒干旱的能力低、成活困难,提出当地绿化建设在树种选择、种植管理等方面的建议.
Abstract
Combining natural environmental factors such as light,temperature,strong winds,and soil in the Seni district of Nagqu city,this study explores the photosynthetic characteristics and environmental limiting factors of plants under harsh environmental conditions in the high cold and high altitude areas of Nagqu city.This results in insufficient accumulated temperature and short growth period during the plant growth season,coupled with frequent occurrence of strong winds and strong noon light radiation throughout the year,resulting in low photosynthetic efficiency and limited photosynthetic products of urban greening plants,As a result,the ability of plants to resist the high cold and drought in Nagqu is low and survival is difficult.Suggestion for local greening construction in terms of tree species selection,planting management,etc.was proposed.
