摘　　要：利用遥感技术与森林资源调查数据,在新疆天西林管局天然林保护工程区开展林地及森林生物量空间变化分析。采用两期遥感影像,通过随机森林的遥感分类技术及生物量模型分别获取两期林地类型分布图和生物量,通过变化分析获取整个天西林管局林地类型面积转化以及生物量及蓄积量的变化及空间分布。结果表明,2010—2016年,非林地变化较明显,转为有林地7 370.1 hm^2,转为灌木林11 536.23hm^2;总体生物量增加了126.00万t,增加比例为2.49%,蓄积量增加了208.74万m^3,增加比例为2.99%。研究结果可为天然云杉林的保护和发展提供科学依据。In this study,remote sensing technology and forest resources survey data were used for analyzing the spatial changes of forest land and forest biomass in natural forest protection project area of Western Tianshan mountains in Xinjiang. Two temporal remote sensing images were used for obtaining forest land distribution and biomass by means of andom forest classification and biomass model. Thus,The change of forest types and biomass were obtained. The results showed that from the year of 2010—2016 the change of non-forestry Land was obvious with 7 370. 1 hm^2 being turned into forest land and 11 536. 23 hm^2 into shrub land. The overall biomass increased by 1. 26 million tons,an increase of 2. 49%,the volume increased by 208. 74 million cubic meters,an increase of 2. 99%.
