揭阳市居住区植物景观调查与评价

Investigation and evaluation of plant landscape in Jieyang urban residential area

在对揭阳市江南新城、金润帝豪湾、联泰花园、御景花园、城市家园5个居住区进行实地调研的基础上,采用层次分析法构建居住区植物景观评价模型,并利用模型对上述5个居住区的植物景观进行评价,结果表明:江南新城植物评价总分最高,植物品种多样,植被层次也较丰富;联泰花园在总体的评分中仅次于江南新城,城市家园总分评价最低,其群落模式比较单一,植物群落空间结构缺乏变化;但总体上揭阳市居住区植物景观相似度较高,缺乏特色,植物景观建设有待进一步提高。

Based on the field investigation of five residential areas （Jiangnan Metro, Kim Im- perial Bay, Luen Thai Garden, Royal Garden, Urban Home）, the evaluation model of plant landscape in five residential districts of Jieyang was established using analytic hierarchy process （AHP） method and was used to evaluate plant landscapes of five residential areas in Jieyang. The results showed that： The score of plant evaluation in Jiangnan Metro was the highest compared to others because of diverse plant species and rich vegetation levels. The score of Luen Thai Garden was the second in plant evaluation. The total score of Urban Home was the lowest because the plant community was relatively simple, and the spatial structure of the plant communities lacked change. In general, the plant landscape in Jieyang lacks of characteristics due to the high plant similarity. Therefore, the plant landscape construction needs to be further improved.
