黄花矶松栽培驯化试验

对生长于北方沙漠、戈壁等干旱地区具有开发应用前景的园林花卉、药用及防风固沙植物,亦为荒漠地区的可食牧草黄花矶松进行了驯化载培试验.结果表明:人工栽培的黄花矶松难度在于种子表层的腊质化,对其种子采用化学方法处理最为有效,育苗出苗率可达73％,田间出苗卒可达54％;其次为机械处理方法,育苗和田间出苗率分别为58％、41％.经人工栽培驯化,黄花矶松可以育苗、移栽、盆栽和田间栽培.栽培方式的不同,可使其根系生长的形态结构有所变化,即田间栽培具有明显的主根,而盆栽则须根发达,说明该种植物人工栽培的适宜性较强.

Exploring preferences for biodiversity and wild parks in Chinese cities: A conjoint analysis study in Hangzhou

There has been a transformation of value orientation from an anthropocentric to eco-centric view in Chinese urban park design. Biodiversity enhancement has been increasingly seen as a prioritised park design aim by landscape designers. This promotes the rise of a novel park style with wild, less manicured appearance in cities, which shows strong contrasts to the traditional park style with ornamental, manicured characteristics. However, in this urban park transformation process, people’s opinion has been almost ignored. This research investigated the importance of biodiversity compared with other relevant urban park attributes (i.e., Facilities, Woodlands, Maintenance, and Seasonal views) identified from preliminary focus groups. The research further predicted preferences between wild and traditional urban parks. Conjoint analysis was used to address these questions. Five urban park attributes (i.e., Biodiversity, Facilities, Woodlands, Maintenance, and Seasonal views) were included in the conjoint questionnaire survey. The survey (N = 187) was conducted with the public and ecology/landscape professionals in Hangzhou, China. Results showed that for professionals, biodiversity was the most important attribute relative to others; for the public, both facilities and biodiversity were the most important attributes. Preferences for the two park styles varied between the two groups: professionals preferred wild parks, whereas the public preferred traditional parks. Yet, public preferences for wild parks were enhanced by improving maintenance levels and providing recreation facilities. The study concluded the appreciation of biodiversity among both the public and professionals. Differences in professional preferences for wild parks compared to the public should be considered when professionals design wild parks in the future.
