云南杜鹃花景观资源分布研究
Study on the Distribution About Rhododendron Landscape Resources in Yunnan
摘要
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.关键词
