Research on Agricultural Ecological Monitoring Technology of 2D and 3D Integration Based on RS and GIS

GIS technology combined with agricultural ecological monitor data was introduced to implement 2-D visualization of ecological monitor and early-warning,more over,the ecological changed region obtained from model database can be read and demonstrated in a 3-D vision.This made the system to function very well in displaying the variations of periodical eco-environment.Taking Laojunshan demonstration area of Yunnan Province,using both 2-D and 3-D modules,the variations of species diversity and site quality in area were analyzed.As a result,two aspects including system construction and system application were discussed respectively.The first part mainly presented the key technical problems;And the next described the utilization of the program in demonstration area.This provides an effective method in agricultural ecosystem warning by adding GIS method into ecological model and implementing multiple dimensions in visualized analyze.
