Analysis of carbon emission mechanism based on regional perspectives is an im- portant research method capable of achieving energy savings and emission reductions. Xin- jiang, an important Chinese energy production base, is currently going through a period of strategic opportunities for rapid development. Ensuring stable socio-economic development while achieving energy savings and meeting emission reductions targets, is the key issue currently facing the region. This paper is based on the input-output theory, and conducts a structural decomposition analysis on the factors affecting energy-related carbon emissions in xinjiang from 1997 to 2007; this analysis employs a hybrid input-output analysis framework of ＂energy - economy - carbon emissions＂. （1） xinjiang＇s carbon emissions from energy con- sumption increased from 20.70 million tons in 1997 to 40.3. million tons in 2007; carbon emissions growth was mainly concentrated in the production and processing of energy re- sources, the mining of mineral resources, and the processing industry. （2） The analysis of the direct effects of the influencing factors on carbon emissions showed that the change in per capita GDP, the final demand structure, the population scale, and the production structure were the important factors causing an increase in carbon emissions, while the decrease in carbon emission intensity during this period was the important influencing factor in stopping the growth of carbon emissions. This showed that while the sizes of xinjiang＇s economy and population were growing, the economic structure had not been effectively optimized and the production technology had not been efficiently improved, resulting in a rapid growth of carbon emissions from energy consumption. （3. The analysis of the indirect effects of the influencing factors of carbon emission showed that the inter-provincial export, fixed capital formation, and the consumption by urban residents had significant influence on the changes in carbon

The ethnic landscape of urumqi has undergone significant changes since the 1980s, which has fostered greater ethnic diversity. However, little is known about the changing patterns of spatial segregation among ethnic groups. By using the urumqi census data from 1982 to 2010, this study examines the level of residential segregation of Uighur from Hart and the level of residential segregation of Kazak, Hui, Mongolia and other ethnic minority groups from the majority Han and Uygur population by the indices of dissimilarity and exposure. Then it assesses a regression between residential segregation and the percentage of the ethnic groups. Finally, it finds out whether there exists a regression between residential segregation and the percentage of the ethnic groups. The result reveals that Kazak population is the most segregated group from Han and Uygur, although the level of segregation has declined from 1982 to 2010. Uighur people experienced lower level of segregation from Han between 1982 and 2000, but has gradually increased, particularly from 2000 to 2010; this unexpected change of the segregation for Uighur group might be associated with 7.5 Events. The findings of the study show that the growth of the Han population is negatively associated with segregation of the ethnic groups in a district, and that the association between the percentage of population and segregation was uniform for Uighur, Hui and Kazak： the higher percentage of an ethnic group in a district, the lower level of segregation.

新型城镇化高质量发展更加注重提升人民群众的幸福感和获得感,加大“15分钟生活圈”公共服务建设力度能有效提升人民群众生活满意度。基于国家“15分钟生活圈”建设要求使用高德地图POI数据,采用核密度估计、缓冲区分析、栅格分析等方法,对乌鲁木齐市公共服务设施的空间覆盖特征进行判断,对住宅小区与各类设施的空间匹配状况进行综合评价。研究表明:(1)不同类型基础公共服务设施的空间布局特征有所差异,既与住宅小区的集聚分布有一定关联,又体现了不同设施的属性特点。(2)不同类型的基础公共服务设施在住宅小区“15分钟生活圈”的覆盖率有一定的差异,以公交站点为代表的公共交通出行的覆盖率最高,便民商业设施中超市、果蔬店、理发店等日常服务设施的覆盖率相对高于银行、电讯营业厅等设施,教育设施中幼儿园覆盖率最高,其次为小学,中学的覆盖率相对较低。医疗设施服务覆盖率在各类型中差别不显著,卫生服务中心、药店、诊所基本都能实现95%的覆盖率。(3.不同类型基本公共服务与住宅空间配置达标率存在较明显区域差异。在人口分布越密集的区域,便民商业、教育、医疗、交通4类公共服务设施均达标的住宅小区比例越高,而人口密度相对较低的外围区域和新建城区医疗和便民商业设施的达标率偏低。(4)乌鲁木齐市建设“15分钟活动圈”应注重加强新建城区的公共服务配套,尤其是便民商业和基层医疗设施,老城区应加强改造过程中公共服务的更新配套。

“一带一路”倡议的实施对促进沿线地区经济合作、互利共赢具有重要意义。基于全球事件GDELT数据库,分别从整体、多类别、多尺度等方面刻画了中国与“一带一路”沿线国家的地缘关系总体特征及其演变过程。主要结论如下:①整体来看,中国与“一带一路”沿线国家历经了“合作为主、分歧较多”“合作增多、分歧减少”“合作稳定、分歧进一步减少”三个阶段;②中国与“一带一路”沿线国家地缘关系事件呈现出“言语促进事件为主且集中,地缘分割事件多国频发”的特点;③国家尺度上的地缘分割事件呈现出先减弱、后增加的趋势,且近年来中国与周边邻国的地缘促进指数呈下降趋势。分析中国与“一带一路”沿线国家地缘关系的时空演变特征,可为我国与“一带一路”沿线国家实现新型合作共赢国家关系提供参考。

城镇化与经济发展水平之间关系的空间格局研究,对区域城镇化与经济发展道路的选择具有更加明确的实际指导意义。基于2000年、2010年人口普查数据,利用统计分析对近期城镇化与经济发展的地级单元格局演变特征进行揭示,借助象限图法对二者关系进行定量识别,结合空间自相关分析对二者关系分布的空间关联效应进行探讨。得出以下结论:①东部沿海地区、内陆省会城市及资源富集型的北方边境沿线部分地级单元城镇化与经济发展水平相对较高;西南地区、青藏高原地区及中原传统农区城镇化与经济发展水平则较低。中国地级单元城镇化与经济发展水平呈显著正相关,在0.01显著性水平下,两个年份二者相关系数分别为0.684和0.741。②地级尺度上城镇化与经济发展关系存在着显著的区域差异,城镇化滞后型、基本协调型和超前型并存。省域内部地级单元二者关系的分布模式具有相似性,即省会城市通常城镇化超前,省内边缘城市多城镇化滞后。③中国地级单元城镇化与经济发展水平关系的分布呈现出显著的空间关联与集聚效应,二者关联集聚程度有所弱化。两个年份,东北地区是中国地级单元城镇化超前型集中分布区,长三角城市群城镇化滞后的态势有所弱化,青藏高原地区城镇化滞后的态势渐趋增强,北方边境沿线资源富集型地级单元由城镇化超前型演变为城镇化滞后型。④中国地级单元城镇化与经济发展关系的类型区变化存在着一定程度的路径依赖效应,"滞后-滞后"型和"超前-超前"型地级单元合占研究单元总数的73.,且二者空间分异特征明显。

Taxonomy plays an important role in understanding the origin, evolution, and ecological functionality of biodiversity. There are large number of unknown species yet to be described by taxonomists, which together with their ecosystem services cannot be effectively protected prior to description. Despite this, taxonomy has been increasingly underrated insufficient funds and permanent positions to retain young talents. Further, the impact factordriven evaluation systems in china exacerbate this downward trend, so alternative evaluation metrics are urgently necessary. When the current generation of outstanding taxonomists retires,there will be too few remaining taxonomists left to train the next generation. In light of these challenges, all co-authors worked together on this paper to analyze the current situation of taxonomy and put out a joint call for immediate actions to advance taxonomy in china.
