Landscape structure and land uese on county level in northeastern Yunnan Province of China—a case study of Huize County

Taking Huize County as an example, the paper analyzed the landscape structure(landscape element structure, landscape type structure, landscape spatial structure, landscape succession structure) and the relations between landscape structure and land use. It was pointed out that the agriculture should be developed in harmony with the landscape structure in the study area.

我国城市污泥中醚类和卤代烃类有机污染物的初步研究

应用GC／MS联机检测技术对我国大陆和香港共11个城市污泥中4种醚类和4种卤代烃类化合物进行分析。结果表明，醚类化合物的总含量在0－7．743mg/kg之间，以双（2－氯异丙基）醚为主，主要分布在兰州污泥和广州污泥中；卤代烃类化合物的总含量在0．007－3．237mg/kg之间，以六氯环戊二烯为主，主要分布在兰州污泥、佛山污泥和沙田（香港）污泥中。污泥中醚类和卤代烃类化合物的种类及其含量与污水来源、污水处理方式、污泥类型、化合物的结构和理化性质等因素有关。     

Energy use and transport correlation linking personal and travel related energy uses to the urban structure

This paper considers relationships between sustainability objectives, transport, spatial design of the built environment and rational use of energy. Conventional transport modelling, housing supply and energy assessment tools are drawn together to provide a common platform for appraisal of city-wide energy use by stationary and mobile sources. The paper outlines methodologies developed for the city of Belfast, Northern Ireland. The paper concludes by briefly reviewing the effect in terms of mobile and stationary energy consumption and travel behaviour of implementing sustainable policy measures in current and future years within the study area.

2000年以来黄河流域土地市场化时空格局演变及驱动因素

基于土地市场交易结构的视角,测算2000-2016年黄河流域104个地级以上城市一级土地市场化程度,综合利用Global Moran's I、G^*_i指数空间统计模型对其时空格局演变特征进行分析,运用灰色关联度分析模型探究土地市场化时空格局演变的主要驱动因素。研究发现：2000-2016年,黄河流域土地市场化水平表现出先持续上升后不断下降的阶段性变化特征,呈现了“东高西低”的空间分异格局。黄河流域土地市场化水平整体具有显著的空间自相关性,土地市场化热点区域以下游主要城市为核心,经历了先加速蔓延、后缓步收缩的时空演进历程。黄河流域土地市场化水平的时空格局演变主要由经济发展水平、产业结构升级、固定资产投资、政府财政收支比、外商直接投资以及区位条件等因素共同驱动,但受我国社会经济发展的阶段性影响,各因素在不同年份的影响程度存在显著的差异性。     

Total nitrogen and community turnover determine phosphorus use efficiency of phytoplankton along nutrient gradients in plateau lakes

Numerous studies support that biodiversity predict most to ecosystem functioning, but whether other factors display a more significant direct impact on ecosystem functioning than biodiversity remains to be studied. We investigated 398 samples of the phytoplankton phosphorus resource use efficiency (RUE_P = chlorophyll-a concentration/dissolved phosphate) across two seasons in nine plateau lakes in Yunnan Province, China. We identified the main contributors to phytoplankton RUE_P and analyzed their potential influences on RUE_P at different lake trophic states. The results showed that total nitrogen (TN) contributed the most to RUE_P among the nine lakes, whereas community turnover (measured as community dissimilarity) explained the most to RUE_P variation across the two seasons. Moreover, TN also influenced RUE_P by affecting biodiversity. Species richness (SR), functional attribute diversity (FAD2), and dendrogram-based functional diversity (FDc) were positively correlated with RUE_P in both seasons, while evenness was negatively correlated with RUE_P at the end of the rainy season. We also found that the effects of biodiversity and turnover on RUE_P depended on the lake trophic states. SR and FAD2 were positively correlated with RUE_P in all three trophic states. Evenness showed a negative correlation with RUE_P at the eutrophic and oligotrophic levels, but a positive correlation at the mesotrophic level. Turnover had a negative influence on RUE_P at the eutrophic level, but a positive influence at the mesotrophic and oligotrophic levels. Overall, our results suggested that multiple factors and nutrient states need to be considered when the ecosystem functioning predictors and the biodiversity-ecosystem functioning relationships are investigated.
