摘要:
 森林城市是城市生态文明建设的重要载体,而林木树冠覆盖水平和木本植物多样性,反映腾冲市城区森林建设成效。通过对树冠覆盖和树种多样性的探讨,以期为腾冲市城市森林建设提供有益借鉴。以2019年Google Earth全色历史影像为基础,利用e Cognition 9.0软件解译,结合多尺度分割算法和最邻近分类法处理。计算其树冠覆盖率及其他土地类型比例,按照随机抽样原则,通过实地调查,选取94个样地。结果表明,腾冲市建成区林木树冠覆盖面积11.01 km2,林木树冠覆盖率为38.90%,腾冲市建成区潜在树冠覆盖面积为3.17 km2,能达到的树冠覆盖率最大理论值为51.10%,各斑块之间进行有机衔接,形成森林生态网络体系,木本植物39 科、83 属、117种,香樟(Cinnamomum bodinieri)优势明显,腾冲市树种数量之间存在明显差异。木本植物多样性水平较高,大科对该区系的构建起重要作用,属种系数70.94%,为极高属系数。腾冲市建成区绿地是以乔灌为主的森林景观,绿地空间利用比较充分。主城区生境较为简单,高树种多样性可能是近些年来腾冲市森林城市建设的结果,进一步说明城市森林建成对城市实现绿色可持续发展起到积极作用。
Abstract:
 Forest city is an important carrier of urban ecological civilization construction,and forest canopy coverage level and woody plant diversity reflect the effect of forest construction in Tengchong city.Through the discussion of canopy coverage and tree species diversity,it was expected to provide a useful reference for the construction of urban forest in Tengchong city.Based on Google Earth panchromatic historical images in 2019,e-Cognition 9.0 software was used to interpret the images,combined with multi-scale segmentation algorithm and nearest neighbor classification method.According to the principle of random sampling,94 sample plots were selected through field investigation.The results showed that the tree crown coverage area was 11.01 km2,the tree crown coverage rate was 38.90%,the potential tree crown coverage area was 3.17 km2,and the maximum theoretical value of tree crown coverage rate was 51.10%.The patches were connected organically to form a forest ecological network system.One hundred and seventeen woody plants were found in 39 families and 83 genera.The dominant species was Cinnamomum bodinieri.There were obvious differences in the number of tree species in Tengchong city.The diversity level of woody plants was high,and large families played important roles in the construction of the flora.The generic coefficient was very high (70.94%),belonging to the highest level coefficient.In conclusion,the green space in the built-up area of Tengchong city is a forest landscape dominated by trees and shrubs,and the green space is fully utilized.The habitat of the main urban area is relatively simple,and the diversity of tall tree species may be the result of the forest city construction in the city in recent years,which further shows that the construction of urban forest plays a positive role in the realization of green and sustainable development of the city.
