With economic development and social progress, geographic information science is playing a more and more important role in tourism development. Many spatial analysis methods have been used in planning and design of scenic development programs. In this paper, the application of geographic information systems is illustratedfrom three perspectives. DEM model, Voronoi diagram and Space syntax are used...
The ecological zone is the smallest unit perceived and relatively consistent in the ecological landscape, and it's also a group of symbiotic community geographically, reflecting the specific climate, soil, vegetation and ecological conditions. There're a number of unique top species, such as tropical rain forest, desert and other ecological domains in this unit. Owing to the continuous progress of...
In road maintenance management, the most important thing is to reduce the unreasonable investment, saving maintenance costs, ensuring all the data of road conditions the accuracy, we must take advantage of computerized technology to make up for shortage of primary management system. Above all we analyze factual requirement about highway maintenance and management system, then we design the frame and...
This work aims to analyze, with the System Dynamics simulation, the impacts of a new supermarket opening in terms of the traffic flows in the surroundings of a determined urban zone, in order to help decision makers to find the most suitable area and the proper number of car parks and counters to satisfy a certain customer level service, avoiding high waiting times and, consequently, customer losses...
By the influence of complex terrain and topography in Karst area, highway construction has inevitable brought a lot of environment problems such as cultivated land occupation, soil erosion and vegetation destroyed, which caused the fragile ecological environment worsening. So how to make full use of the land resource and keep ecological environment balance will be the important and necessary topic...
CLUE-S is a tool that can predict future land use changes. CLUE-S had been successfully applied to simulate land use change in Bandung region. The dependent variable was land use which classified into seven classes (water, forest, others, built area, plantation, dry land, and rice field). The independent variables were social economical aspect, biophysical aspect, accessibility and climate. The result...
Cellular automata (CA) has been proven to be an effective method in simulating urban spatial development. The paper describes the concept model of a cumulative CA model. By putting the model into practice using ArcGIS as basic spatial data processing platform, a prototype system is built. The system is designed to process vector datasets as its data sources. Several cumulative values are calculated...
With the original data as basis, evaluation of cultivated land quality was carried out in Yidu County with the aid of GIS and the fuzzy matter-element proximity cluster model. The procedure of the evaluation goes:(1)Use the principal component analysis method to determine factors which affecting cultivated land quality;(2) extract correlatographs through vectorization with the aid of ArcGIS, put them...
Grassland fire is a serious and common disaster in Inner Mongolia, China and it is a kind of extremely complex natural phenomena influenced by various factors. The design aims to simulate the fire trend based on GIS and scientific grassland fire spread model and finally provides assistant decisions. The system will be used in Inner Mongolia Emergency Response Platform.
