As human society is now facing a huge ecological crisis. Strengthen the management of forest resources, to achieve the sustainable development of forestry has become more and more national consensus. Forest resources survey of forest resources management is the fundamental work. Its purpose is to prepare for the forestry division, planning, preparation of forest management plans and programmes, the establishment of forest resources files and identify forest use and forest logging quota programmes to provide the basic information and the basis. Its major task is to identify the types of forest resources, structure, quantity, quality, distribution, growth and decline in the resources of law, an objective reflection of natural, economic conditions, a comprehensive evaluation, accurate survey of forest resources, the plans of materials, statistics And the investigation report.how to use 3S technology to minimize the wild ground investigation work to improve the quality of the findings to real-time, accurately grasp the status of forest resources, forestry at home and abroad has always been a concern of remote sensing technology and research workers in the hot.In this paper, forest resources survey on the basic concept of basic elements and tasks, and the traditional survey by the existing problems, then elaborated on the forest reserves of high spatial resolution remote sensing estimation of the need for research methods, technical routes And details of the forest reserves of high spatial resolution remote sensing estimation theory, the use of today’s popular programming technology, the underlying development of remote sensing estimation of forest reserves, national forest resources to meet the needs of investigation.Finally, I use object-oriented programming language VC + +, using object-oriented development method, based on this theory of a number of modules have been studied and Implementation. The image of a common format for analysis, commonly used image-processing software to read and display images of the method of analysis, the constraints of the massive image data read and display the speed of the cause of an in-depth study proposed Fruitful improved algorithm, and the realization of the substantial increase computing speed, making use of remote sensing images on-site survey of forest resources efficiency has been greatly improved. And to improve the existing remote sensing image processing software on the reader and the massive data show that the method of remote sensing images.
