In recent years, China has been committed to strengthening environmental governance and trying build a sustainable society in which humans nature develop harmony. As new urban construction concept, sponge city uses natural ecological methods retain rainwater, alleviate flooding problems, reduce the damage water environment, gradually restore hydrological balance of area. The paper presents review from its inception systematic demonstration. this paper, research gaps are discussed future...

As urbanization has profound effects on global environmental changes, quick and accurate monitoring of the dynamic changes in impervious surfaces is great significance for protection. The increased spatiotemporal resolution imagery makes it possible to construct time series obtain long-time-period high-accuracy information about surface expansion. In this study, a three-step method based trajectory segmentation was developed extract expansion using Landsat applied Xinbei District, Changzhou,...

Understanding the dynamics between public disaster assistance, damages, and social vulnerability at county-level is crucial for designing effective mitigation strategies. This study utilized Local Bivariate Moran Index (LBMI) geographically weighted regression (GWR) models to examine spatial patterns relationships vulnerability, assistance in contiguous US counties from 2001 2021. LBMI results reveal that has predominantly been directed towards post-disaster recovery efforts, with a...

Location prediction is an attractive research area because of its potential application in location-based services such as advertisements, route planning and so on. In this paper, a method based on mining history trajectory logs proposed to predict people's next location for transition from current location. The training samples model considers temporal features containing daily hourly well spatial like the which are all extracted historical dataset. learning process, location-prediction...

In recent years, power grid accidents have occurred frequently and higher requirements been placed on their safety operation. current management in the world, there is an effective practice that uses a unified standard for structuring accident case database based database, conducts quantitative analysis to cope with risks. However, not management. Case-based reasoning (CBR) such process solves new problems solutions similar past problems. It works by matching problem historical cases order...

Land use/cover changes (LULC) are complicated and regionally diverse. When mining regional patterns, the use of a spatial relationship that is determined without considering correlation among geographical objects can lead to problematic results, e.g. mistakenly treating unrelated as adjacent. Additionally, traditional prevalence measures unstable for uneven datasets such LULC, wherein some land-use change types show small numbers quantities, valuable rules categories may be ignored....
