淄川太河矿泉水保护与开发利用现状及产业发展

淄川太河矿泉水水源地位于淄博市淄川东南部山区的太河镇境内,是淄博市主要水源地。该水源地矿泉水类型以含锶型弱碱性水为主,也有少量较奇缺的锂锶复合型弱碱性水,资源丰富,品质优良,是一个不可多得的矿泉水聚集区。但由于管理不规范等原因,淄川矿泉水产业面临市场竞争力弱,开发秩序混乱、可持续发展能力不强等问题。开发利用过程中应做到:坚持保护为先确保矿泉水资源可持续开发、实施综合整治规范矿泉水产业秩序,坚持科学开发努力实现资源效益最大化。

利用遥感技术,使用eCognition软件的面向对象分类技术,对RAPIDEYE卫星影像进行分类识别,从而快速、准确的监测小麦种植面积,为冬小麦财政补贴提供数据和技术支持。以兖州市为例,行政区面积6.501 9万hm2,小麦监测面积3.1715万hm2,小麦面积监测精度达到了90.5%。     

中国西北地区城市网络体系分析——基于民营企业布局

从民营企业视角对中国西北地区的城市网络体系进行实证分析,透视民营企业对其城市网络形成的作用。利用民营企业的分布数据,借鉴城市网络分析方法,从服务值、连通性、网络性3个方面对西北地区的城市网络体系进行了分析。基于民营企业视角,西北地区的城市构成了以西安和乌鲁木齐为主副双核、省会城市为核心节点、其他城市可作为其辐射区域的网络系统,且基于民营企业的城市网络体系尚处于初级发展阶段。     

环渤海地区中心城市金融竞争力评价及辐射研究

以环渤海地区中心城市为研究区域,通过建立城市金融竞争力评价指标体系,运用突变级数法、主成分分析法、层次分析法对环渤海地区中心城市金融竞争力进行综合评价,并通过威尔逊模型揭示了中心城市的辐射范围。环渤海地区中心城市金融发展不平衡,北京的城市金融竞争力遥遥领先于其他城市;环渤海地区并未形成一个紧密联系的金融辐射网络,金融一体化还不成熟,仍有金融盲区的存在;各中心城市在发挥自身优势的同时应打破地区间行政壁垒,优势互补,协同发展,带动环渤海地区金融发展。     

Geospatial spreadsheets with microscale air quality visualization and synchronization for supporting multiple-scenario visual collaboration

A major obstacle of the interdisciplinary communications for decision-making is that each participant prefers the solution from their own area because current collaboration systems cannot effectively mediate among many alternatives. If a visual collaboration system could display multiple alternatives in a single visual presentation, users would be able to compare alternatives with only a few variables, where all other parameters are fixed, at least from a visual perspective. In this study, we developed a visualization tool to support a microscale air quality (MSAQ) management group, the members of which often need to compare the effects of many alternative control methods. The main achievements of this study are: (1) three-dimensional (3D) visualization of the MSAQ using a 3D city model and (2) development of a geospatial spreadsheet (GS) to facilitate visual comparisons, thereby improving decision-making by making it easy to compare differences based on realistic visual display items. A questionnaire-based survey showed that use of the GS could generate a shared perspective and provide a spatiotemporal context for the participants, thereby making it easy to compare, mediate and reach decisions when confronted with many alternatives.     

开平市1960—2012年灰霾的气候变化特征

根据开平气象观测站1960—2012年观测资料,采用滑动平均、线性趋势分析等统计方法,分析了开平市近53年灰霾的气候变化特征。结果表明,开平市年平均灰霾日数为21.1 d,年最多132 d,年最少0 d,总体呈上升趋势,上升速率为1.72 d/年,特别是2000年以来年灰霾日上升趋势最为显著,上升速率达10.01 d/年。其中,20世纪80年代中后期、90年代中期和21世纪初是3个明显的上升阶段,21世纪以来,年平均灰霾日数58.4 d,是20世纪80年代平均值的近17倍。开平市灰霾以轻微为主,比例达57.6%,其次是轻度,比例为22.6%。另外,采用日均值、14：00实测值判别法得到的开平市灰霾日整体变化趋势与人工记录较一致,但3种方法统计的多年平均灰霾日相差较大,其中,日均值法计算的多年平均霾日数较14：00实测值法多13.8 d。     

Empirical Analysis of City Contact in Zhujiang （Pearl） River Delta,China

In traditional urban geography, city contact research is a classic study element in city research. In general, researchers use the traditional gravity model to characterize the contacts that exist between two cities. The traditional gravity model assumes ideal condi- tions, but these preconditions and their results often do not exist in realistic conditions. Thus, we used a modified gravity model to char- acterize the city contacts within a specific region. This model considers factors such as intercity complementarities, government inter- vention, and the diversity of the transportation infrastructure which is characterized as the transportation distance instead of the tradi- tional Euclidean distance. We applied this model to an empirical study of city contact in the Zhujiang （Pearl） River Delta （PRD） of China. The regression results indicated that the modified gravity model could measure city contact more accurately and comprehen- sively than the traditional gravity model, i.e., it yielded a higher adjusted R2 value （0.379） than the traditional gravity model result （0.259）. Our study also suggests that, in addition to urban-regional and metropolitan development, the complementarities of the basic functions of cities at the administrative and market levels, as well as the corporeal and immaterial levels, play very significant roles in the characterization of city contact. Given the complexity of city contact, it will be necessary to consider more relevant influential fac- tors in the modified gravity model to characterize the features of city contact in the future.
