摘要
为了探究云南省杜鹃花景观资源分布状况,对省内分布面积10000 m2以上的66个杜鹃花海景观进行调查,利用地形DEM数据和土壤酸碱度pH值数据定量分析6种本土常见优势杜鹃花品种的生长适宜区.结果表明:景观资源呈现出全省广泛分布、滇西北相对集中的区域特征,以及高海拔(平均海拔2771 m)、高落差(最大高差3014 m)的立体特征.基于土壤和地形条件,本土优势杜鹃花品种的泛生区和共生区的空间分布与景观资源的区域分布特征一致.为研究立体景观花期垂直变化,分析2018-2021年轿子山景区的垂直气温特征,基于积温理论对立体景观花期变率进行估算试验,得到在景区中高山温凉地带,海拔每上升100 m花期约推迟3.4 d;在高山寒凉地带,海拔每上升100 m花期约推迟5.5 d.
Abstract
To explore the distribution of Rhododendron landscape resources in Yunnan Province,a survey was conducted on 66 Rhododendron fields with an area of more than 10000 m2 in the province,and the growth suitable area of 6 common indigenous dominant Rhododendron species was quantitatively analyzed using terrain DEM data and soil pH value data.The results showed that the landscape resources exhibit a wide distribution throughout the province,with a relatively concentrated region in the northwest of Yunnan.There are distinctive features of high elevation(average elevation of 2771 m)and significant relief(maximum height difference of 3014 m).Based on soil and terrain conditions,the spatial distribution of the indigenous dominant Rhododendron variet-ies'ecological and symbiotic zones align with the regional characteristics of landscape resources.In order to study the vertical change of three-dimensional landscape flowering period,the vertical temperature characteristics of Jiaozi Mountain scenic spot from 2018 to 2021 were analyzed,and the variation rate of three-dimensional land-scape flowering period was estimated based on the accumulated temperature theory.It was found that in the middle mountains in the scenic spot,the flowering period was delayed about 3.4 days per 100 meters;in the more colder and higher areas,the flowering period was delayed by about 5.5 days per 100 meters.
