Urban cultural space(UCS) has been of great social and economic value for sustainable development, and the existing researches about it mainly focus on some specific aspects, such as historical heritage or cultural service facility. However, UCS hasn't been quantitatively assessed as an independent system with clear definition and comprehensive classification. Thus, we present a quantitative analysis based on the statistic of UCS provision in different categories between 44 sub-districts in Xi'an and find its inequalities. Xi'an urban land use data and population data of sub-district level are introduced in the analysis process with GIS,SPSS and MATLAB. Our results indicate that inequalities of UCS in Xi'an are mainly reflected in three aspects, including categories, geospatial and population. Among the four categories of UCS, historical heritage and cultural park account for higher percentage, while cultural service facility and religious space are lower. The inequalities in geospatial could be estimated from two indicators. The first indicator named cultural space rate ranges from 0 to 66.88%, while the other named distance between residential and cultural space varies from 100.47 m to 2004.75 m. The inequalities in population could be assessed by cultural space per capita and Gini coefficient. The results indicate that per capita ranges from 0 m^2 to 214.79 m^2. The Gini coefficient of Xi'an is 0.86, which means that the UCS distribution in population is extremely inequitable. Our studies would further the research on UCS and provide constructive suggestions in urban planning and policy formulation to ensure adequate UCS provision and improve its distributional order in Xi'an.

目的为探明了解冷藏即食预包装熟肉制品中单核细胞增生李斯特菌(单增李斯特菌)污染情况及潜在风险,本研究针对短保质期的冷藏即食预包装熟肉制品开展单增李斯特菌定量污染风险调查。方法2022年5~8月,从成都市采集样品64份,依据采用传统培养分离鉴定和RT-PCR分子检测方法进行单增李斯特菌的定性和定量检测,分离菌株提取DNA后进行二代全基因组测序并开展相关流行病学特征分析。结果检测结果发现64份即食熟肉样品中,6份样品检出单增李斯特菌,检出份数为6/64。6份阳性样品均由某同一工厂生产,其中5份为卤肉三拼样品。定量检测结果表明,卤肉三拼的单增李斯特菌污染水平为30~200 CFU/g;单增李斯特菌阳性的猪肉样品污染水平为<10 CFU/g。阳性样品中的6株分离菌株经全基因组测序分析鉴定为单增李斯特菌,均含有LIPI-1毒力岛相关基因,多序列位点分型发现主要的序列型(ST)为ST3(n=2)和ST121(n=2),其次是ST8和ST9。单核苷酸多态性(SNP)结果分析发现同一工厂分离到的单增李斯特菌菌株LM22071911和LM22080802之间检测到23个SNP差异,单增李斯特菌株LM22062706和LM22080806之间检测到13个SNP差异,说明在该工厂加工环节存在两种克隆群的单增李斯特菌直接传播的风险。结论成都市部分市售冷藏即食预包装熟肉制品污染多种李斯特菌,需加强源头控制。

For the last decade, chytridiomycosis was considered to be caused by a single species of fungus, Batrachochytrium dendrobatidis （Bd）, but a second chytrid species, Batrachochytrium salamandrivorans （Bs）, was recently isolated from an in- fected Salamandra salamandra in the Netherlands. To date, Bs has only been found in the Netherlands. To assess whether Bs is present in China, we analyzed a total of 665 samples, including 425 wild samples, 41 preserved specimens, and 199 captive sam- pies, from 30 different species, including both urodeles and anurans. Our sample sites covered 15 provinces in China. All of the samples tested negative for Bs, resulting in a 95% confidence limit for a prevalence of 0.6%. The absence of Bs observed in this large-scale survey in China has significant implications for amphibian conservation and for border trade management strategies intended to control amphibian diseases. We strongly recommend the continued close monitoring of Bs to verify the status of this potentially devastating amphibian fungus in China .
