摘要: 在三维空间分析等技术的支持下，以森林防火监测型资源的配置评价和优化为研究对象，在森林火险精准区划的基础上，采用监测率、盲区率、重复率等指标来评价森林防火监测型资源配置的合理性，并根据这些指标来对监测型资源的配置进行优化。以浙江省临安市板桥乡为例，实现了从数字高程模型（digital elevation model，DEM）中快速提取山顶点，并结合区域森林火险等级，对每个山顶点做可视域分析和叠置分析，在监测型资源给定的情况下，求算出该乡镇的监测率、盲区率、重复监测率、高火险区域监测率等指标，并根据预先设定的参数来对监测型资源的配置进行优化，使防火资源配置更加科学、合理、有效。图2表5参９Abstract: Based on the precise rating of forest fire dangers，the paper had a research on the evaluation and optimization of the allocation of the forest fire monitoring resources with three-dimensional spatial analysis technology to evaluate the rationality of the allocation of the forest fire monitoring resources through the indicators including monitor rate，blind spot rate，repetition rate and etc. The monitoring resources were optimized based on these indicators. Taking Banqiao Town of Linan City as an example，the research had a quick extraction of mountain peaks through DEM. On the basis of the regional forest fire danger rating，visual domain and overlay analysis of each mountain peak was conducted. Under the situation of the given monitoring resources，it calculated this towns monitor rate，blind spot rate，repetition rate，monitor rate of high fire risk areas and other indicators. According to the pre-set parameters，it optimized the allocation of the monitoring resources，making resources allocation more scientific，reasonable and effective.［Ch，2 fig. 5 tab. 9 ref.］
