Wetland park is one of the city's major ecological infrastructures, undertaking the dual functions of improving the ecological environment and providing recreational places. Studying the reasonable construction methods of the wetland park is very important for its sustainable development. In this paper, a wetland park with an area of 173.5 hectares located in Zhangzhou City, Fujian Province, China is taken as an example to show how to apply the concepts and measures of resource saving and environment friendliness to the three development phases of planning, construction and management of the park. Measures of resource saving include land conservation, water resource conservation, energy conservation, vegetation optimization, application of low carbon construction techniques, indigenous materials and intelligent technologies used in management. Environment friendly measures include development intensity control, man-made wetland construction, friendly materials adoption, fibre resource using wooden plank, road building on stilts, topsoil and native vegetation protection during construction, noise control, pesticide usage reduction in management, bio-safety disposal of garbage and tourists capacity control. Resource saving and environment friendly wetland park construction can effectively promote the sustainable development of the park.Keywords

Food quality and safety has become the key problem that China faces today. As a new type of urban agricultural development model which combines organic food production with leisure tourism, the organic food leisure park performs multiple functions, including production, leisure, ecological and social. As the important measure to promote food quality and safety, organic food leisure park has vast future development potential. Based on the "seed to feed idea" of RUAF Foundation, this work takes the construction of organic food leisure park in Qinyang City, Henan Province, China as an example. The discussion is made in three aspects: environmental quality, function layout and the ecological cycle model. The results show that the combination of organic food production and leisure sightseeing effectively improves the comprehensive benefits of organic agriculture.Keywords

‘Sponge city construction’ has led to higher requirements for rainwater absorption in urban green space. When the rainwater absorption capacity of typical underlying layers in urban green space, i.e., plants and soil, is limited, mulch can often make up for the deficiency in the rainwater absorption capacity of the green space. This study focuses on four types of mulch: loose pine cone scales, broadleaf oak bark, coconut shells, and sawdust, and conducts rainwater harvesting to measure their rainwater retention efficiencies. The results are as follows: in terms of mass, coconut shells weighed 3.87 times their original mass after absorption; in terms of volume, coconut shells had the highest absorption rate per unit volume at 0.65 mL/cm3. Sawdust reached an absorption rate per unit volume of 0.58 mL/cm3. Within the first 10 minutes of rainwater harvesting, sawdust reached its maximum retention volume of 98.7%, followed by coconut shells, oak bark, and loose pine cone scales at 76.6%, 75.1%, and 65.7%, respectively. Highly absorptive mulch is conducive for enhancing rainwater retention, and urban green space and mulch rainwater retention provide greater flexibility for coping up with intense rainstorms. Therefore, mulch has broad application prospects in urban green space, especially those in semi-arid regions. This study recommends adopting mulch as the third underlying layer after soil and plants in major urban green space.Keywords

Turf and ground cover plants are major components of ground coverage of urban green spaces. Canopy interception is a critical link in the atmospheric water circulation of plant elements. Leaf area index (LAI) and degree of canopy cover are major factors affecting canopy interception of grass coverage. Six plant varieties in Xinxiang City, Henan Province, China, namely, Festuca arundinacea, Trifolium repens, Oxalis corymbosa, Liriope angustissima, Zephyranthes candida and Iris tectorum were experimented in this study. Their LAI, interception capacity per unit leaf area, and degree of canopy cover were measured using weighing-scanning, soaking and image processing methods, respectively, with the interception capacity per unit area calculated. Our results show that Liriope angustissima, Oxalis corymbosa and Iris tectorum have comparatively high LAI; Zephyranthes candida and Festuca arundinacea have comparatively high interception capacity per unit leaf area; Liriope angustissima, Iris tectorum and Oxalis corymbosa have comparatively high interception capacity per leaf area; Oxalis corymbosa, Trifolium repens and Liriope angustissima have comparatively high degree of canopy cover. We conclude that a comprehensive consideration of LAI and degree of canopy cover of grass plants is preferred in urban greening plans, in order to achieve better performance of canopy interception. This conclusion also provides a reference to stormwater management and ecological water usage in urban green spaces.Keywords
