Jabodetabek and Greater Bandung Metropolitan areas experiencing the phenomenon of urban expansion which has caused both metropolitan areas to be more connected and become a mega-urban area by a corridor through a conurbation process. Karawang regency is part of the region in the Jakarta-Bandung corridor. The increasing number of population in the region will encourage the addition of number and types of public facilities.

Abstract:

The aim of this study was to identify the spatial pattern of biomass distribution in the revegetation of the post-mining area in PTVI. The nearest neighbour analysis method by comparing the distance of an individual was used to determine the spatial biomass distribution pattern in the post nickel mining revegetation area of PTVI. The nearest neighbour analysis was used to explain the distribution pattern of locations using a calculation that considers the distance, number of locations and acreage. This analysis produced a final result in the form of an index ranging from 0 until more than 1. I

Abstract In past decades, gradient pattern analysis has been used effectively to characterize the spatial pattern of population distribution in cities worldwide. Most of these studies have focused only on individual case studies or a limited number of cities. However, measuring, analyzing, and understanding complex spatial patterns of city population distribution requires comparative studies that extend beyond the isolated case of cities. Therefore, the present study analyses the spatial pattern of population distribution along the gradient distance from the city centers of the world’s 50 larg

Spatial patterns through diffusion-driven instability are stationary structures that appear spontaneously upon breaking the symmetry of the spatial domain, which results only from the coupling between the reaction and the diffusion processes. This paper is concerned with a modified Leslie–Gower-type model with cross-diffusion and indirect predation effect. We first prove the global existence, non-negativity and uniform boundedness for the considered model. Then the linear stability analysis shows that the cross-diffusion is the key mechanism of spatiotemporal pattern formation. Amplitude equat

Abstract:

Gianyar Regency, as one of Bali’s leading tourist regions, continues to develop tourism destinations in support of the regional tourism development plan and vision of “Realizing High-Quality, Competitive, Sustainable, and Prosperous Cultural Tourism.” The development of Gianyar Regency’s tourism potential requires an understanding of the spatial relationships based on the typology and distribution patterns of tourism destinations. This research aimed to reveal the typology of tourism destinations in Gianyar Regency, determine the distribution patterns of tourism destinations in Gianyar Regency

Abstract:

Identifying the factors that drive the spatial distribution of fires is one of the most challenging issues facing fire science in a changing world. We investigated the relative influence of humans, land cover and weather on the regional distribution of fires in a Mediterranean region using boosted regression trees and a set of seven explanatory variables. The spatial pattern of fire weather, which is seldom accounted for in regional models, was estimated using a semi-mechanistic approach and expressed as the length of the fire weather season. We found that the drivers of the spatial distributi

Exploring the spatial differentiation of PM2.5 concentrations in typical urban agglomerations and analyzing their atmospheric health patterns are necessary for building high-quality urban agglomerations. Taking the Xiamen-Zhangzhou-Quanzhou urban agglomeration as an example, and based on exploratory data analysis and mathematical statistics, we explore the PM2.5 spatial distribution patterns and characteristics and use hierarchical analysis to construct an atmospheric health evaluation system consisting of exposure–response degree, regional vulnerability, and regional adaptation, and then iden

Abstract:

The large-scale spatial distribution of northern shrimp (Pandalus borealis) larvae was analyzed in the Gulf of St. Lawrence during the spring of 1986 and 1987. Although sites of emergence are related to the principal aggregation areas of adult shrimp, it appears that the currently fished aggregations may not represent isolated populations. The uniformity of developmental stages and the wide-spread distribution of the first larval stage were consistent with the hypothesis of synchronous larval emergence among the northern Gulf shrimp The structured pattern of larval spatial distribution was not

Abstract:

Seed dispersal, interacting with environmental disturbance and management across heterogeneous landscapes, results in irregular weed spatial distributions. Describing, predicting, and managing weed populations requires an understanding of how weeds are distributed spatially and the consequences of this distribution for population processes. Semivariograms and kriged maps of weed populations in several fields have helped describe spatial structure, but few generalizations can be drawn except that populations are aggregated at one or more scales.

Macaranga gigantea was one of the pioneer species who started the succession process after the forest fires and grew as dominant species. Therefore, the information on the spatial distribution pattern of M. gigantea is required as necessary data to determine the strategy for managing forest after forest fires. This study aimed to map out of distribution and identified the spatial distribution pattern of M. gigantea.

Abstract:

Benford’s law states that the first digits of numbers in any natural dataset appear with defined frequencies. Pioneering, we use Benford distribution to analyse the geo-location of cities and their population in the majority of countries. We use distances in three dimensions: 1D between the population values, 2D between the cities, based on geo-coordinates of location, 3D between cities’ location and population, which jointly reflects separation and mass of urban locations. We get four main findings. Firstly, we empirically show that mutual 3D socio-geo distances between cities and populations

Dengue fever disease increases alongside urbanization rate in tropical countries. Hence, the need to visualize the distribution pattern of increases is vital for the management of dengue cases, especially in Malaysia. Thus, the dengue surveillance system is proposed for the monitoring of dengue cases using computer-generated modeling for spatial distribution patterns, which is important for management and control. The present study performed distribution and spatial pattern analysis of dengue cases reported in the growing Seremban district in Negeri Sembilan, Malaysia in 2008 and 2009. The pur

Abstract:

Taxis play a crucial role as an on-demand transportation mode in developing countries due to perceived inefficiencies of cities’ public transportation systems. However, studies on the locational distribution of taxis in urban areas are limited, despite the need to improve passenger service quality by balancing the demand and supply of taxi services. Notably, taxi stations possess distinct characteristics compared with other public transport stations that serve passengers directly; in contrast, taxi stations solely support taxi drivers in locations where they begin and conclude their work.
