At the same time as the gentrification movement has increasingly become a mean of urban renewal in some cities around the world, the connotation of the gentrification theory has been greatly enriched, and it has attracted the attention by different disciplines such as geography, planning, and management. In particular, with the rise of the cultural and creative industries in the 1990s, the renovation of old industrial zones led by creative parks has become one of the most important strategies for urban renewal, industrial upgrading and urban marketing, similar to the Western society's gentrification. And how to analyze the logic behind this phenomenon and reveal the dynamic mechanism of gentrification in the old industrial districts has become a research hotspot and difficulty in the study of gentrification and urban planning in the 21st century. In this article the Ningbo Hefeng Creative Plaza was chosen as case, questionnaires and interview data were used and the rooted theory and structural equation model were applied to construct and verify the dynamic mechanism of gentrification in the old industrial districts covering space production, push-pull mode and creative clusters. The findings can be concluded here: (1) The creative restoration process of Hefeng Creative Plaza presents a typical gentrification phenomenon, with characteristics of the openness and multi-landscape dominated by high-end office buildings, privatization of thesettled enterprises, the characteristics of creative production factors and the externalization of production relations, as well as group characteristics of younger population, feelings of creativity and service-oriented, creativity and service-oriented. (2) The phenomenon of gentrification in Hefeng Creative Plaza is a social space replacement formed by the push-pull method under the production of space in the old industrial districts. That is, spatial fix is dominated by the production and reproduction relationships linked by capital, power, and creativity; The material space creation and creative practice of architectural planners and creative class form a spatial representation; Spatial representation promotes the endogenous development and evolution of creative clusters, catalyzes cultural consensus and identity based on cultural, ideal and emotional experiences, and sublimates into a representational space. the Logical path of "sensual recognition of local elements → rational constraints of capital elements and relationship forces → coordination of local elements, capital elements and relationship forces → feedback of relationship forces" has been formed, which has activated the spatial evolution of the old industrial areas. (3) The development of Hefeng Creative Cluster depends on the interaction of cultural atmosphere, office environment, economic location, government policy and social relationship network.

National unification is a crucial issue for regional stability and national rejuvenation, which is, however, out sight of the mainstream geographers in China. In fact, human geography has a more comprehensive and systematic theoretical framework for interpreting the process of national unification than political science and law studies have, especially due to the rapid rise of political geography. This paper aims to probe into the mechanism and implications of national unification based on a series of theoretical establishments, such as state sovereignty, geopolitics, post colonialism, and new imperialism. We attempt to deconstruct the process of national unification into three-dimensional restructuring of space, namely, geo-political relationship, capital space, and cultural identification. The case of Germany's unification in 1990 represents the process of unification after the collapse of the Berlin wall, which can be regarded, first, as a result of upheaval of international political pattern, say, the end of the Cold War, due to the decline of the former Soviet Union while the rise of neoliberal capitalists. Second, the unification of Germany is a durable process that takes place in economic integration between West and East Germany, during which the capitalist imperialism has been playing an invisible role in speeding up barbarous expansion of capital. Third, the cultural imperialism that has permeated into the people's ideology and perception of state has been chronically influencing the formation of the identity as "one Germany".

The interprovincial geographical entities are the key areas of Targeted Poverty Alleviation and the regional integrated management. Based on the geographical names dictionary, the thematic maps and the atlas of provincial administrative boundaries of China, we established a database of interprovincial physical geographical names (ITPGN) and analyzed the spatial pattern of the ITPGN from the aspects of numerical features, spatial variance and spatial association. The problems and the impacts of the separate management of the interprovincial geographical entities were further discussed and four suggestions were offered accordingly. There were 11325 ITPGN including 4243 water ITPGN and 7082 terrain ITPGN in China. Hunan Province had the largest number of the names, and Shanghai had the smallest number. In addition, the spatial variance of the terrain ITPGN was larger than that of the water ITPGN, and the ITPGN showed a significant agglomeration phenomenon in the southern part of China. Regional terrain and population were important factors influencing the spatial patterns of ITPGN. The largest number of ITPGN was found in areas where the relative elevation was between 1000-2000 meters, and where the population was between 40-50 million. The separate management led to apparent differences in the development goals, development patterns, and management modes in the different parts of the same interprovincial physical geographical entities. These problems would reduce the efficiency of resources utilization, affect the integrity of natural reserves, hinder the cultural exchange and intensify socioeconomic differences among different parts. It was suggested that the government should explore unified management mechanism for interprovincial physical geographical entities, establish special organizations directly under the central government to manage the interprovincial entities, build up interprovincial cooperation zones to realize coordinated development of the interprovincial areas, and take the interprovincial physical geographical entities as unified units for the application of national parks or other protected areas.

Taking 342 cities in China as an example, this paper explores the spatial correlation between haze (PM_2.5) and tourism flows, as well as analyzes the impact of haze on tourism flows and the spatial spillover effects from 1998 to 2016 by using bivariate LISA (Local Indications of Spatial Association) Model and Spatial Panel Dubin Model. The results show that the spatial distribution patterns of haze (PM_2.5) pollution and tourism growth in China are both high in the eastern region and low in the western region, showing some regularity related to the factors, such as terrain and urban development on both sides of Hu Huanyong population line. Haze and tourism flows (including domestic tourism flows and inbound tourism flows) show both significant spatial agglomeration and spatial dependence during the study period, indicating that haze pollution has great spatial effect on tourism flows. The area where haze curbs tourism flows is expanding. The increase in the number of HL (High-Low) -type cities, the expansion of LH (Low-High) -type agglomeration area and the hollow phenomenon of LH-type agglomeration that appear in north and central China all show that tourists tend to travel to the cities with low haze pollution. The inverted U-shape curve relationship between haze pollution and tourism flows illustrates that the classical Environmental Kuznets Curve (EKC) hypothesis is suitable for tourism growth in the cities of China. The negative impact of haze on inbound tourism flows is significant. Both haze pollution and tourism flows have positive spatial spillover effects. Combining haze management with other measures, such as economic development, tourism development, ecological protection, traffic construction, we can create a beautiful environment for tourism development and achieve a healthy, coordinated and sustainable high-quality development of international and domestic tourism.
