城市景观多功能区湿地水质分异及其人类影响

以南京市仙林大学城为案例,在对该区景观功能区划分基础上,对各景观功能区典型湿地进行了1年的水质监测,揭示了不同景观功能区湿地水质季节变化特征,并利用模糊数学综合评价法对不同景观功能区湿地水质进行综合评估,进一步分析了各景观功能区湿地水质与人类影响强度的关系。结果表明:1)南京市仙林大学城湿地水质季节波动性明显,春夏季节水质较差,在Ⅲ类水以下,秋冬季节在Ⅲ类水以上。在各污染因子中,全磷污染负荷最大,平均值为0.11mg.L-1。2)不同景观功能区湿地水质空间差异明显,其优劣排序为:高校景观区>农业景观区>休闲景观区>商业景观区。3)湿地水质和人类影响强度的负相关关系明显(R2=0.938)。

Eco-economic Background of Hilly-Gullied Loess Region and Optimized Eco-productive Paradigm of Small Watersheds

A thorough analysis on its natural environment as well as social economic status of the hilly-gullied loess region is presented. A small watershed, the dominant landscape unit of the region, has been singled out for further and specific study on landscape pattern and function, its social and economic distinctions. The authors proposed several principles based on its eco-economic background study, which includes water balance and efficient use principle, co-development of grass and agro-forestry principle, location optimization principle. Integrated with detailed analysis of a small watershed, an eco-productive paradigm for the loess land's development based on a small watershed scale was worked out. It consists of circle pattern with villages at core for high efficient agriculture production, hierarchical pattern along the slope for eco-economic development, point-axis pattern for commodity production and circulation in small watersheds and core-margin pattern for exchanges among watersheds.

Study on Plant Landscape Design of Urban Comprehensive Park

The urban comprehensive park is the main body of the urban environment construction, and the plant landscape is the most important landscape element of the comprehensive park. It is helpful for the landscape design of the comprehensive park to improve the environmental quality and the sustainable development of the city. Taking the ＂Nanjiang Park＂ in Xiaoshan District of Hangzhou as the research object, the landscape design of plants was explored and analyzed. The results showed that there were significant differences in the application forms of plant land- scapes in different functional zones in comprehensive parks. The specific forms of the garden elements had different needs of plant landscape construction. According to the results of case studies, it found that comprehensive parks could improve the functions, create the aesthetic sense, enhance the atmosphere and enhance the taste through plant landscape design. In addition, corresponding suggestions were put forward according to the current situation with the aim to provide references for the future plant landscape design related with garden greens.

Spatio-temporal Pattern of Multifunction Tradeoffs and Synergies of the Rural Landscape:Evidence from Qingpu District in Shanghai

The configuration of a multifunctional rural landscape is critical for its protection.Although studies on multifunctional rural landscapes have been conducted,there is a lack of information regarding the spatiotemporal characteristics and tradeoff/synergy relationships of rural landscape functions in the time series on the administrative unit scale.The purposes of this study were to(1)analyze the spatial-temporal distribution characteristics of the tradeoff and synergy from the perspective of multifunctionality for efficient use of rural landscape resources and(2)formulate regional sustainable development policies to minimize the conflict between people and nature.Aiming at the scientific representation of landscape function and the quantification of landscape multifunctional relationships,and by taking Qingpu District of Shanghai as an example,six kinds of rural landscape functions were constructed according to the functional framework of"productive function,living function and ecological function".Based on the data for 1980 to 2018,the characteristics of variations of multifunctional tradeoff and synergy relationships of the rural landscape in 184 administrative villages were studied by the methods of Spearman rank correlation coefficient analysis and bivariate spatial autocorrelation.The following results were obtained.1)The fine division of rural landscape function types was realistic and necessary for analyzing the regional multi-function relationships in the regions with rapid development.In the process of rapid urbanization,the rural landscape functions of urban suburban areas changed under the combined action of natural resource endowment,social and economic conditions and other internal and external factors.As a result,the agricultural production function could not replace the economic development function and become the function of rural landscape production.The research results of Qingpu District showed that the agricultural production function was no longer the primary functional form,yet the economic development function became the dominant function in this area.2)Temporal and spatial analysis methods of rural landscape functions can accurately and comprehensively reflect the evolution of the characteristics of multifunction tradeoffs and synergies.According to the Spearman rank correlation analysis of the multifunction value of the rural landscape in the time dimension,the results masked the differences of resource and environment carrying capacity caused by the differences of regional landscape resource endowment in the spatial dimension.3)The spatial and temporal differences of the multi-functional tradeoffs and synergies of the rural landscape in Qingpu District from 1980 to 2018 were significant.There was significant heterogeneity of tradeoffs and synergies between functions in the spatial pattern,with clustering characteristics.Meanwhile,as for the temporal pattern,the tradeoffs and synergies of functions changed differently in terms of Moran’s I and the correlation coefficient.The results of this study can provide scientific references for urban-suburban-rural space reconstruction and regional sustainable development.
