草坪是城乡园林绿化的重要组成部分 ,它能绿化大地 ,保持水土、净化空气、减少和降低噪音 ,使人们身心更健康 ,更舒适。冷季型草坪草是贵州地区最适宜的栽培草种 ,近几年来在贵州种植较多 ,但由于选种单一 ,播种量过大 ,整地方法不当等 ,从而使草坪适应性差 ,抗病力弱 ,青绿期短 ,且投资大。因此 ,筛选适应性广 ,抗逆性强 ,青绿期长 ,观赏价值高的草坪草种 ,以及探索经济实用的草坪建植管理技术有着重要意义。1 试验概况试验于 1 998年~ 2 0 0 1年在本所试验场进行。试验建植面积 1 90 0m2 。建植地地势平坦 ,海拔 970m ,年均温度 1 5℃… 相似文献

草坪草混播是草坪建植中一种常用的方法,常用于冷季型草坪的建植,可以使不同草种优势互补,从而具有更强的适应性。以黑麦草、高羊茅、早熟禾为例,两两按比例混合播种,并评价其密度变化。 相似文献

草坪是城市绿化不可或缺的组成部分。但由于建筑、树木等遮挡住光照度,导致很多草坪遮荫成为十分普遍的问题。所以,遮荫草坪养护管理是一大难点和重点。基于此,本文首先提出遮荫对冷季型草坪草生长与生理特征的影响,进而探究相应的建植、养护措施。 相似文献

Urban parks can bring multiple health benefits to seniors and thus are important to their lives. This study investigated seniors’ spatial distribution, preferred activity zones, and activity intensity during park visits. We used GPS trackers to collect spatial location information and accelerometers to record metabolic equivalent of energy (MET) at an interval of 10 s, and examined differences in activity intensity according to activity zone type. Data from 286 seniors in two large urban parks in Shanghai, China were included. We identified eight park activity zone types: pathway, paved open space, sports area, children’s playground, lawn, water, other natural area, building, and other area. Grid cells of 5 m by 5 m were created and hotspot analysis was utilized to identify the activity zones most frequently used by seniors. ANOVA post-hoc analysis was applied to investigate the variance between activity zone cells in terms of mean visit point counts, total visit point MET, and average MET. We also utilized latent class analysis to identify distinctive subgroups of seniors.The results indicate that seniors’ spatial distributions vary vastly both between and within park activity zones. Of the eight zone types, paved open space was used most frequently, and seniors were most active on pathways. Other natural area also had high usage, and featured higher average activity intensity than sports area, water, and building and other area. Children’s playground had higher average activity intensity than lawn or water. Finally, three distinctive groups of seniors were identified: short-stay active walker, long-stay light walker, and short-stay transient. These findings have direct implications for park design practice. Paved open space and pathways should be carefully designed based on the specific seniors’ activity patterns. Furthermore, seniors’ needs should be considered in the design of playgrounds in parks, where they accompany their grandchildren, and of other natural area, where they stretch their bodies and enjoy fresh air. The diverse activity patterns of the subgroups of seniors should be addressed in future studies. 相似文献
