Evaluation on Forest Resource Quality of Pinus thunbergii Coastal Shelterbelt in Shuangdao Forest Farm of Weihai City

Taking Pinus thunbergii coastal shelterbelt forest in Shuangdao Forest Farm of Weihai City as the research object, the evaluation index system of forest resource quality was constructed by using the method of analytic hierarchy process. The weight of each evaluation index was multiplied by the corresponding grade assignment of the measured value, and then the forest resource quality index of the forest subcompartment was obtained by adding, and then the forest resource quality index of the forest management unit was calculated by the area weighted average method. The results showed that naturalness, proportion of dominant tree species and soil thickness had important impacts on forest resource quality, and the contribution rates were 0.1292, 0.1195 and 0.1127, respectively. The scores of the first 2 indexes were relatively low, which reduced the evaluation results. The forest resource quality index was 0.61 and the evaluation grade was 'good'.
