Research on Development Rules of Forest Hazard Caused by Masion Pine Caterpillars Based on GIS
Abstract:

Although the integrated technique of management for Mason pine caterpillar have developed a systemic research for about half a century, it is still unable to meet the demand of forestry sustainable development with social and economic development. The monitoring and management system of forest insects and diseases based on "3S" and internet technology have already been established in many countries. However it is still in very preliminary stage and far from being perfect in our country at present. In this paper, we utilize remote sensing of data Qianshan county, Anhui province and primarily discuss the correlation between the occurrence and development of pine caterpillar and terrain, roads with residential areas in virtue of spatial analysis functions of GIS such as overlay, proximity and spatial statistics analysis. Dynamic change information of pine caterpillar among different years is also compared. Finally this article educed various factors influencing pine caterpillar and master space-time spatial expansion rule of pine caterpillar. It is beneficial to early forecast and prevention of pine caterpillar. The result has validated some empirical knowledge, such as geographic distribution and developing process of pine caterpillar. It shows the feasibility of forecasting pine caterpillar quantitatively and orientationally by using GIS.
