Construction Of Landscape Pattern Simulation System In Mining Area

With the development and utilization of high-intensity iron ore resources,long-term overexploitation will cause land damage and landscape damage.This change is a comprehensive reflection of the impact of mining process on regional ecosystem.In order to more intuitively reflect the landscape and ecological change of the mining area,determine the damage degree and reconstruction difficulty of the ecological environment of the mining area,carry out two-dimensional planning and three-dimensional reconstruction of the landscape pattern of the mining area,build a simulation system of the landscape pattern of the mining area,and carry out innovative research from the following aspects:1)The evaluation system of landscape reconstruction potential is designed,the influencing factors affecting the difficulty of landscape reconstruction in mining area are determined,six levels of potential reconstruction in mining area are defined,the evaluation method of landscape reconstruction is proposed,and the most complete construction of the evaluation system is realized.2)This paper studies the combination of landscape planning analysis,landscape reconstruction evaluation system and GIS system,and the method of realizing landscape planning analysis under GIS system,as well as the self-evaluation of landscape reconstruction potential.3)A landscape pattern simulation prototype system is designed.The system uses C ?? as the development language,Arc Engine as the core development library of GIS functions,Scene Control as the three-dimensional landscape display library,and develops and implements the C / S architecture system on the visual studio platform.In addition to the basic GIS data management function,the system realizes landscape analysis,landscape pattern reconstruction potential self-evaluation,and realizes the display of 3D landscape in the system.Finally,a mining area in Tangshan is used as the research object to simulate the system,analyze and get the characteristics of the phase transfer track of each element of landscape and the changes of landscape types from 2000 to 2015,and evaluate the mining area as grade VI through the landscape reconstruction evaluation module,which needs to carry out ecological reconstruction,and use the system to carry out twodimensional landscape planning for the research mining area,so as to realize the threedimensional field of landscape reconstruction scheme Scene generation and simulation.Figure 50;Table8;Reference 90...
