On the Formative Factors of Urban Narrative Space

With the continuous development of society,the urban space has already met the basic functional needs of the people.As the crystallization of the ideology of mankind and the social development,the urban space exerts an effect on the people on both the material level and the spiritual level.The urban space inherits the urban culture and influences people’s feelings,and the proper narrative space can meet the increasing emotional needs.This paper analyzes the three formative factors of the urban narrative space—the temporal factor,the spatial factor and the diversified event factor,showing the readers a clearer narrative space and laying foundation for the further study on narrative space theory.

时空异质性视角下华北地区碳足迹评估及驱动因子分析

碳足迹是衡量碳排放的重要指标,削减碳足迹是实现“双碳”目标的前提条件。华北地区作为我国高耗能、高排放的集中区域,客观量化碳足迹并探究主要驱动因子对加快推进碳减排具有重要意义。为此,论文基于IPCC法对华北地区“十五”至“十三五”期间的碳足迹进行测算,运用标准差椭圆分析碳足迹的分布及转移特征,使用地理探测器识别碳足迹的主要驱动因子。研究发现:(1)“十五”至“十三五”期间碳足迹总量经历了“先增长—后下降”两个阶段,由“十五”期间的425452万吨上升至1066353万吨,而后逐渐下降到“十三五”期间的898908万吨。(2)标准差椭圆呈稳定的“南—北”分布,重心分布于山西大同和河北张家口之间,呈向西北方向偏移趋势,已偏移72.56千米。(3)能源强度、产业结构、城镇化率对碳足迹驱动因子解释力度较大,且关键交互因子均含有能源强度、产业结构、研发投入。华北地区不同时期碳足迹分布及影响因子存在时空差异,在制定碳减排政策时应充分考虑区域碳足迹的时空异质性。

GIS-Based Factorial Ecology and Social Public Space of the Twin City of Ramallah and Al-Bireh, West Bank, The Palestinian Authority

In the present research, a factorial ecological approach using factor analysis was employed to evaluate the dimensionality of the urban social structure of the twin city: Ramallah and Al-Bireh, West Bank, the Palestinian Authority. Through factor analysis, the 41 variables were reduced to four factors with an eigenvalue > 1.0. These factors explain 77.07 percent of the total variables used in the study. Factor I contributes 28.419% of the total variance proportion of input variables, labeled as “family, housing, and public spaces factor”. Factor II accounts for 19.57% of the variance proportion, designated as” housing and urban public spaces”. Factor III is strongly correlated with variables referring to the characteristics of the head of the family, and the availability of public spaces, and thus, is designated as “head of the family and public spaces”. It explains 16.68% of the total variance. Finally, factor IV explains 12.406% of variance proportion, and is strongly associated with variables pertaining to a lack of public social spaces. Consequently, factor IV is termed “lack of public spaces”. The spatial distribution of factor scores related to factors I to IV was mapped using Arc GIS in order to analyze the spatial patterns of the recognized four factors. It is worth noting the factor IV, which refers to the lack of urban social space and, urban public space, which persists in the twin city, and will continue to persist in the future. The lack of urban open space and public social spaces is closely connected to migration, emerged housing pattern, and family status dimensions focused on factors I to III, continuous confiscation of the Palestinian lands, and the construction of Israeli settlements. Currently, the twin city is extremely overcrowded with stone/concrete buildings at the expense of public space which has declined continuously over the last three decades. Nevertheless, the analyzed spatial pattern of factor scores indicated the homogeneous character of the urban society of the twin city. Based on the urban eco-logical models which seek to characterize the Western, non-Western, Israeli, and Arab-oil producing (e.g., Kuwait) urban structures, it is difficult to elaborate a specific Palestinian urban ecological model with reference to the models developed elsewhere.

Spatial-Temporal Evolution Characteristics and Driving Factors of Agricultural Space in Jianghan Plain from the Perspective of “Three-Zone Space”

Studying the agricultural spatial distribution characteristics of Jianghan Plain from 2000 to 2018 and its spatial-temporal transformation with ecological space and urban space is of great significance for optimizing the spatial structure of the country, enhancing the supply capacity of agricultural products, and ensuring food security. The research results show that during the period from 2000 to 2018, the agricultural spatial concentration in the area along the “Xiaogan-Jingzhou” link was relatively high, and the areas with large declines were mainly distributed in the flat areas between the Yangtze River and Han River;the space is continuously reduced by the occupation of ecological space and urban space, and ecological space and urban space have been improved respectively;agricultural space has been transformed into ecological space, and the largest urban space has been transformed. Ecological space has been transformed into agricultural space and urban space. Less urban space has been transformed into agricultural space and ecological space.

Factorization of Operators in Krein Spaces and Linear-Fractional Relations of Operator Balls

We consider plus-operators in Krein spaces and generated operator linear fractional relations of the following form: . We study some special type of factorization for plus-operators T, among them the following one: T = BU, where B is a lower triangular plus-operator, U is a J-unitary operator. We apply the above factorization to the study of basical properties of relations (1), in particular, convexity and compactness of their images with respect to the weak operator topology. Obtained results we apply to the known Koenigs embedding problem, the Krein-Phillips problem of existing of invariant semidefinite subspaces for some families of plus-operators and to some other fields.

一种新的基于factor curve的变形控制方法

本文提出了一种新的基于ｆａｃｔｏｒｃｕｒｖｅ的变形控制方法．Ｂａｒｒ的整体非线性变形和Ｗａｔｔ的时空因子曲线方法都不同程度地依赖于某种解析表达式，不便于进行统一的控制．作者首次对因子曲线进行了分类，提供了一种统一的控制方式，因而非常适合于动画系统．把因子曲线本身作为可变参数的动画控制方法不仅包含了Ｂａｒｒ的ｔａｐｅｒｉｎｇ和ｔｗｉｓｔｉｎｇ操作，而且还包含了Ｗａｔｔ的因子曲线变形控制方法．因而动画师有更多的余地对变形进行有效的控制．

综合地质与经济因素的城市地下空间开发潜力探析

以往考虑地质条件约束的地下空间开发潜力评价已经越来越难以满足现代城市地下空间精细化规划与开发需求。本文在考虑地质因素的城市地下空间开发评价指标体系的基础上,考量引入经济因素,初步建立了综合经济与地质因素的评价指标体系,进而应用层次分析法和多目标线性加权法构建地下空间开发潜力综合评价模型。以我国东南部地级市N市c区为研究案例,在考虑地质条件的基础上,引入房价与人均GPD,借助GIS软件实现空间数据可视化。研究结果表明,研究区开发潜力呈现由北至南逐渐降低的特征;c区地下空间高潜力开发区、中等潜力区、低潜力区、差潜力区面积分别占区域总面积的15.74%、37.66%、32.17%、15.43%。对比不同约束条件下地下空间开发潜力的评价结果可知,综合考虑地质与经济因素下的c区地下空间开发潜力高的地区比单一考虑地质条件下开发潜力高的地区面积占有所降低,因此将经济要素纳入地下空间开发评价指标体系考量范围,能够促使城市地下评估更具全面性,以期推动更符合时代发展趋势的城市地下空间的开发评价、规划及利用。

Combination and distribution of reservoir space in complex carbonate rocks

This paper discusses the reservoir space in carbonate rocks in terms of types,combination features,distribution regularity,and controlling factors,based on core observations and tests of the North Truva Oilfield,Caspian Basin.According to the reservoir space combinations,carbonate reservoirs can be divided into four types,i.e.,pore,fracture-pore,pore-cavity-fracture,and pore-cavity.Formation and distribution of these reservoirs is strongly controlled by deposition,diagenesis,and tectonism.In evaporated platform and restricted platform facies,the reservoirs are predominately affected by meteoric fresh water leaching in the supergene-para-syngenetic period and by uplifting and erosion in the late stage,making both platform facies contain all the above-mentioned four types of reservoirs,with various pores,such as dissolved cavities and dissolved fractures,or structural fractures occasionally in favorable structural locations.In open platform facies,the reservoirs deposited continuously in deeper water,in an environment of alternative high-energy shoals（where pore-fracture-type reservoirs are dominant） and low-energy shoals（where pore reservoirs are dominant）.
