Analyzing Asymmetric City Connectivity by Toponym on Social Media in China

Chinese Geographical Science 2021年第1期31卷 14-26页

作者： YE Xinyue GONG Junfang LI Shengwen department of landscape architecture and Urban Planning Texas A&M University College StationTX 77843 USA School of Geography and Information Engineering China University of GeosciencesWuhan 430074China Key Laboratory of Urban Land resources Monitoring and Simulation Ministry of Natural ResourcesShenzhen 518034China

The connectedness between cities has become one of the most widely discussed topics in urban and regional research in the mobile and big data era. One problem identified is the asymmetric city connectivity, partially due to data availability. We present a data-driven approach based on location and toponym(place name) extracted from social media data, to assess the asymmetric connectivity between cities. The assumption is that a higher frequency of occurrences of the name of city i in posts located in city j would imply that the city i is more influential than other cities upon city j. In addition, we’ve developed a group of measurements such as the relatedness index, impact index, link strength index, dependence index, and structure similar index to characterize such interactions. This framework of connectivity measurements can also be used to support smart planning taking into account the evolving interplay among cities. The space-time structure of urban systems in China is examined as the case study.

Assessing the effects of long-term recreational activities on landscape changes in Abant Natural Park,Turkey

Journal of forestry Research 2016年第2期27卷 453-461页

作者： Gunay Gakir Haldun Miiderrisoglu Latif Giirkan Kaya department of forestry and Environmental Sciences Naturaland Applied ScienceGumushane UniversityGumushaneTurkey department of landscape architecture Faculty of ForestryDiizce UniversityDuzceTurkey Faculty of Engineering and architecture Mehmet Akif ErsoyUniversityBurdurTurkey

Natural, protected areas offer many possibili- ties for recreation in rural areas such as camping, one of the most popular activities. The system established for pro- tected areas in Turkey aims to provide a foundation for conserving areas for recreation. One such area, Abant Natural Park, is convenient for visits from Turkey＇s two most populated metropolitan areas, Istanbul and Ankara. It also attracts tourists from other regions and countries. The aim of the present study was to evaluate the vegetation loss and land cover changes due to picnic/camping, transhu- mance, and construction over 40 years （1966-2004） in the park using data on visitor numbers, vegetation patches, corridors and connectivity. For evaluating landscape vari- ables, remote sensing data and aerial photos were used. When aerial photos were imported into the ERDAS Imagine program, ground control points identified, and individual images orthorectified, land degradation was not found in the use of camping areas. Moreover, manmade areas （road, car park and hotel） observably increased, thus decreasing the forest lands. The findings show that the land use types that have had the greatest ecological impact are transhumance and construction of hotels, which also require infrastructure development. The intensity of the ecological effects mandates precautions to lessen the impacts and the need for continuing assessment to ensure sustainable use of the area.

Exogenous ethylene influences flower opening of cut roses (Rosa hybrida) by regulating the genes encoding ethylene biosynthesis enzymes

引用

Science China(Life Sciences) 2005年第5期48卷 434-444页

作者： MA Nan1, CAI Lei1, LU Wangjin2, TAN Hui1 & GAO Junping1 1. department of Ornamental Horticulture and landscape architecture, China Agricultural University, Beijing 100094, China 2. department of Horticulture, South China Agricultural University, Guangzhou 510642,China department of Ornamental Horticulture and landscape architecture China Agricultural University Beijing China department of Horticulture South China Agricultural University Guangzhou China

The purpose of this paper is to investigate the differential responses of flower opening to ethylene in two cut rose cultivars, ‘Samantha’, whose opening process is promoted, and ‘Kardinal’, whose opening process is inhibited by ethylene. Ethylene production and 1- aminocyclopropane-1-carboxylate (ACC) synthase and oxidase activities were determined first. After ethylene treatment, ethylene production, ACC synthase (ACS) and ACC oxidase (ACO) activities in petals increased and peaked at the earlier stage (stage 3) in ‘Samantha’, and they were much more dramatically enhanced and peaked at the later stage (stage 4) in ‘Kardinal’ than control during vasing. cDNA fragments of three Rh-ACSs and one Rh- ACO genes were cloned and designated as Rh-ACS1, Rh-ACS2, Rh-ACS3 and Rh-ACO1 respectively. Northern blotting analysis revealed that, among three genes of ACS, ethylene-in- duced expression patterns of Rh-ACS3 gene corresponded to ACS activity and ethylene production in both cultivars. A more dramatic accumulation of Rh-ACS3 mRNA was induced by ethylene in ‘Kardinal’ than that of ‘Samantha’. As an ethylene action inhibitor, STS at concentration of 0.2 mmol/L generally inhib-ited the expression of Rh-ACSs and Rh-ACO in both cultivars, although it induced the expression of Rh-ACS3 transiently in ‘Kardinal’. Our results suggests that ‘Kardinal’ is more sensitive to ethylene than ‘Samantha’; and the changes of Rh-ACS3 expression caused by ethylene might be related to the acceleration of flower opening in ‘Samantha’ and the inhibition in ‘Kardinal’. Additional results indicated that three Rh-ACSs genes were differentially associated with flower opening and senescence as well as wounding.
