Understanding users’ spatial distribution in forest park is crucial for providing visitors with quality recreation experiences and for park planning and management. Utilizing users’ spatial distribution data, this study aims at investigating associations between trail use level and trail spatial attributes, through examining two large urban forest parks (Gongqing forest park and Paotaiwan forest park) in Shanghai, China. Users’ spatial distribution was measured utilizing GPS trackers with the interval of 10 seconds. This study conceptualizes trail spatial attributes as trail metric attributes and trail configurational attributes. Trail metric attributes include trail mean distance to gates, length, width and level of enclosure, which are calculated based on park map and on-site observation. We computed trail configurational attributes utilizing space syntax theory, which comprise measures of global integration, control, and connectivity. Trail connection with features/facilities, visual connection with water and shading are included as covariate variables. In total, we obtained 134 valid samples in Gongqing forest park and 210 valid samples in Paotaiwan forest park for analysis. Multivariate regression analyses indicate that when involving covariate variables, consistently in both parks, a greater trail usage is significantly related to trail shorter mean distance to park gate, trail width wider than 3 meters, higher global integration and higher control values. Collectively, these four trail spatial attributes explained 31.7 % (p < 0.001) and 27.3 % (p < 0.001) of the variances in trail use level in Gongqing forest park and Paotaiwan forest park. These findings provide direct implications to park designers and managers for providing visitors with different desirable social conditions, and ultimately improve users’ experiences and satisfactions. 相似文献

Abstract The aim of this study was to investigate whether forest experience had a positive impact on cognitive function. Cognitive function refers to a person's ability to intellectually process by which one becomes aware of, perceives, or comprehends ideas. It involves all aspects of perception, thinking, reasoning, and remembering. Sixty university students participated in this study. We compared the restorative effects on cognitive functioning of interactions with forest versus urban environments. To measure participants’ cognitive function and mood state, Trail Making Test B and Profile of Mood States were used in this study. The results of this study indicated that participants’ cognitive function was significantly improved when they walked in forest (i.e. time taken to complete the task was shortened by more than 7 seconds), but not when they walked downtown. In addition, participants’ mood also positively changed when they walked in forest. The results of this study confirmed Kaplan's attention restoration theory (ART). ART has emphasized the importance of cognitive functions from interaction with natural environments such as forests. 相似文献

Data of the "Static Fertilisation Experiment Bad Lauchstädt" were used to identify the effect of different fertiliser application on yield, various energetic parameters as well as on carbon and nitrogen balance of the long-term trial in a selected time period (1991-2000). The fertiliser regimes considered, are neither mineral fertiliser nor farmyard manure (without/without), mineral NPK and no farmyard manure (NPK/without), no mineral fertiliser and 10t ha m 1 a m 1 farmyard manure (without/10), mineral NPK and 10t ha m 1 a m 1 farmyard manure (NPK/10), no mineral fertiliser and 15t ha m 1 a m 1 farmyard manure (without/15), as well as mineral NPK and 15t ha m 1 a m 1 farmyard manure (NPK/15). The farmyard manure was only applicated to root crops. The crop rotation included sugar beets, spring barley, potatoes and winter wheat. In most cases, the treatment NPK/10 yielded in the most favourable results whereas the treatment without/without was the most unfavourable one. Sugar beets were - followed by winter wheat - the most profitable crops, potatoes the most unfavourable one. The fossil energy input was highly variable; it ranged from 4.1 to 24.3GJ ha m 1 a m 1 depending on fertiliser regime and crop. The total yield (based on main products and by-products) varied from 2.1 to 20.1t dry matter ha m 1 a m 1 , corresponding to an energy output between 3.4 and 33.6GJ ha m 1 a m 1 . The energetic parameters energy gain (net energy output) and energy intensity ranged form 25.5 to 315GJ ha m 1 a m 1 and from 143 to 1824MJ GE m 1 , respectively. The carbon balances resulted the highest C gain with the exclusive mineral fertilisation (NPK/without), followed from the treatment NPK/10. The same applies for the nitrogen balances. 相似文献

On the basis of results from stationary long-term trails the accumulating effects of different mineral-organic fertilization on the uptake and the balance of nutrients as well as DL-soluble P and K contents in soil was examined. The long-term varied fertilization affected the uptake and the balance of nutrients considerably. With farmyard-manure supplied doses of P and K caused a significant higher increase of the plant-available soil contents in comparison to the straw-fertilization and also to the pure mineral PK-supply. The organic fertilization obviously favours by increased humus contents and a thereby promoted biological activity the solubility behavior of phosphorus and potassium. 相似文献
