中文摘要 屋顶绿化是削减城市热岛强度的重要手段,其改善街区近地热环境的能力受街区形态的影响。文章基于局地气候区(Local Climate Zone, LCZ)框架,对上海4个优化类与转型类产业园样区中共115个产业街区进行形态分类,从各样区的主导类区中共选取12个典型街区,在上海夏季7月标准气象日条件下进行ENVI-met热环境模拟。结果表明:上海工业街区夏季白天近地温度最高的时刻与屋顶绿化降温效果最佳的时刻均为14∶00;上海夏季白天产业街区覆盖屋顶绿化前后近地热环境的改善具有统计显著性;铺设屋顶绿化后,LCZ5和LCZ3组街区的降温均值分别为-0.12℃与-0.07℃,且LCZ5类区的降温效果更佳。因此,从缓解热岛现象出发,上海产业园区若推进屋顶绿化建设,应优先考虑以LCZ5为主导形态类区的转型类产业园区。

英文摘要 Rural plantscape is an important component of rural human settlements, and rural residents' perception of rural plantscape is of great significance for rural development. The paper selects 28 beautiful villages in Jinan, Shandong Province, and divides them into 3 types in accordance with the type of development, i.e., agriculture domination, business travel service and balanced development. Through field research, SD method and on-site interviews, rural residents' perception of plantscape in rural public spaces is evaluated, and its impact factors are studied, with a view to providing a reference for optimizing the plantscape design of the villages of different development types. The results show that the residents living in beautiful rural areas in Jinan are highly satisfied with the rural plantscape, and 70.94% of them hold a satisfactory attitude. There are differences in the SD evaluation of various types of rural areas. The agriculture villages are characterized with abundant space, few plant species, and small changes of plants in the four seasons. The business travel service dominated villages are characterized with rich plant species, large changes of plants in the four seasons, and insufficient interactive experience. The balanced development oriented villages are characterized with multiple plant species, natural wilderness, and rich in beauty. Atmosphere factors have the greatest impact on the perception of plantscape. The evaluation shows that the perception of rural plantscape is scored at 31.00, 21.81, and -31.53, respectively, for balanced development oriented village, business travel service dominated villages and agriculture dominated villages. Therefore, rural plantscapes in the villages of different development types have different characteristics and problems. The creation of rural plantscape should be adapted to local conditions to give more play to their advantages, fully consider local characteristics to address existing problems in a targeted manner, improve the rural living environment and improve residents' quality of life.
