辽宁西北部主要园林绿化树种叶片生长规律

采用标准化主轴和聚类分析方法,研究辽宁西北部主要树种叶片的比叶面积和异速生长规律。结果表明：种间叶片面积与生物量的共同斜率为1.052,其中46个树种斜率小于1.0,1个树种等于1.0,8个树种大于1.0;种间叶片含水量与生物量的共同斜率为1.052,其中42个树种斜率小于1.0,13个树种大于1.0。各树种比叶面积变化范围在48.83~276.52 cm²•g^-1,当欧氏距离为15时,可将树种划分为3类。辽宁西北部主要树种叶片生物量与面积、生物量与含水量之间总体呈等速生长,而各树种的异速生长指数却明显不同。树种比叶面积相对较低是其适应贫瘠环境的自然结果。因此,在干旱半干旱地区城市绿化和造林中,应选择比叶面积较小的树种。     

中水灌溉绿地对土壤微生物数量的影响

通过对深圳市罗芳污水厂厂区长期中水灌溉绿地土壤的调查,探讨中水灌溉对土壤微生物类群数量的影响。结果表明,长期中水灌溉下土壤微生物类群数量与清水相比有增加的趋势。在土壤表层(0~20 cm),以细菌的增加最显著(P0.05),增幅达43.49%~76.22%;其次是放线菌,增幅达7.11%~15.39%;真菌的变化最小,增幅仅达0.96%~3.44%,但放线菌和真菌差异不显著(P0.05)。土壤含水量与土壤微生物呈不同程度的正相关关系,且中水灌溉下较清水变化更显著。从而表明中水灌溉绿地能够促进土壤微生物的繁衍,有利于植物的生长发育。

Designating a greenbelt around the city of Riga, Latvia

Latvian legislation demands that forest protection belts are established around all cities and towns. The main goal of a protection belt is to provide suitable opportunities for recreation to urban dwellers and to minimise any negative impacts caused by urban areas on the surrounding environment. Legislation states the main principles to be adopted, which include the maximum area of protection belts, their integration in territorial development plans and restrictions placed on forest management activities. The largest part of the forest area around Riga is owned by the municipality of Riga, which, as a result, has two competing interests: to satisfy the recreational needs of the inhabitants of Riga, and to maximise the income from its property. In order to compile sufficient background information to solve this problem, the Board of Forests of Riga Municipality initiated the preparation of a proposal for the designation of a new protection belt.The proposal was based on the development and application of a theoretical framework developed during the 1980s. The analysis of the recreational value of the forest (5 classes of attractiveness) was carried out based on categories of forest type, dominant tree species, dominant age, stand density, distance from urban areas and the presence of attractive objects. Information was derived from forest inventory databases, digital forest maps and topographic maps. Additional information was digitised and processed using ArcView GIS 3.2. Local foresters were asked about the recreation factors unique to different locations, such as the number of visitors and the main recreation activities. From a recreational point of view and taking into account legal restrictions and development plans for the Riga region, it was proposed to create three types of zones in the forest: a protection belt, visually sensitive areas and non-restricted areas.

Combining the preferences of residents for neighborhood green spaces and conservation of avian diversity: Case study from Beijing

Cities in China support higher human population densities compared to those in western countries; consequently, the high pressure placed on cultural ecosystem services (CES) provision of residential green spaces might hinder overall human wellbeing and the maintenance of avian diversity. Thus, this study aimed to identify how to meet the main preferences of citizens for residential green spaces while simultaneously enhancing bird diversity in city neighborhoods, generating a win-win scenario for human needs and biodiversity. This study was implemented using 568 questionnaires for residents and GLMM for bird-environment statistical analyses. Residents in Beijing preferred higher levels of bird species richness than individual abundance in neighborhoods. Residential green space appeared to serve as the movement corridor for some rare species, indicating the importance of promoting the presence of migrant bird guilds, which is currently incidental. The cultivation of fruit-bearing shrubby plants was supported by most city residents, and would also promote the presence of migratory birds in green spaces. In contrast, while increasing the width of residential green spaces would benefit migratory birds, it had less public support. This multi-disciplinary study clearly demonstrated that both the quality of life of humans in cities and biodiversity conservation could be efficiently incorporated in green space plans, even under highly urbanized circumstances.     

Nature orientation and opportunity: Who values and who has opportunity for satisfactory green spaces in proximity to their place of residence

Urban green spaces (UGS) provide important contributions to people. Yet, UGS planning requires better understanding of by whom and where such contributions are being valued or missed. Based on a mixed-methods online survey and choice experiment with residents of Wellington in Aotearoa New Zealand, we analyse how much and why residents value UGS and their benefits when deciding where to live and how socio-economic and spatial factors might impact nature orientation and opportunity for satisfactory local UGS. We find that local UGS are an important residential choice criteria for the majority of respondents, especially in the context of Wellington’s intensification plans. However, we show that socio-economic and spatial factors significantly impact whether someone values and is satisfied with UGS in proximity to their place of residence. Our findings call for careful scoping of a city’s population and spatial structure when planning for equitable UGS provision. More holistic approaches to green space planning are needed to address contextualities and the complex interdependencies between nature orientation and opportunity and to plan for green space distributions that provide opportunities now and help shaping nature orientation for future generations.
