图2 局部尺度和区域尺度(100 m、150 m、200 m和250 m海拔段)水生昆虫群落分类多样性和功能多样性指数的海拔格局。黑色实线表示多样性指数对海拔梯度存在极显著(P < 0.01)和显著(P < 0.05)的线性或二次响应关系, 灰色实线表示轻微显著(P < 0.1)的线性或二次响应关系, 黑色虚线表示无显著(P > 0.1)的线性或二次响应关系。

Fig. 2 The relationship between taxonomic and functional diversity indices and elevation at local and regional (elevational band across 100 m, 150 m, 200 m, and 250 m) scales. Black solid line indicates highly significant (P < 0.01) and significant (P < 0.05) linear or quadratic relationships, grey solid line indicates marginally significant (P < 0.1) linear or quadratic relationships, and black dotted line indicates non-significant (P > 0.1) linear or quadratic relationships.
