Along with the development of computer techniques,the application of computer in three-dimensional visualization simulation of plant growth process has been paid more and more attention.Taking Cunninghamia lanceolata as an example,the morphological parameters from the perspective of the visual simulation were designed and the trees' morphological characteristics were analyzed based on the survey data.Combined with IFS(Iterated Function System) under the control of the growth curve,by using Object-oriented design methods,and according to API and model rendering technology provided by DIRECTX9.0,a three-dimensional visualization system on the growth and development of C.lanceolata individual tree were developed on the.NET and DIRECTX9.0 platforms,which realized the static and dynamic three-dimensional visualization simulation.

通过调查攸县黄丰桥国有林场近几年森林灾害对林业及森林的影响和造成的损失,特别是2008年初的50年不遇的冰冻灾害对林场的损失十分巨大,其森林生态效能将倒退10年以上;其次,森林火灾的危害也触目惊心.林场各项建设的负担越来越重,森林灾害造成的损失得不到补偿.为此,就如何建立森林保险对林场进行了客观的调查分析,并提出了对策和措施,解决了投资主体受益少与受益主体不投资的矛盾.
