摘要
天山云杉(Picea schrenkiana var.tianschanica)是新疆山地涵养水源、防风固沙的重要树种,对新疆森林生态系统的形成和维护等方面具有举足轻重的作用。温度、降水量、土壤、地形等生态因子是研究森林生态系统的重要数据基础。本数据集以新疆伊犁地区的遥感影像、DEM、气象和土壤等多源数据为基础,采用多尺度分割、最近邻分类和空间分析等方法,生成了2014年伊犁地区天山云杉分布区生态因子数据集,包含温度、降水量、日照时间、坡度、坡向、土壤类型6种生态因子。本数据集采用TTA Mask精度验证等方法进行了严格的数据质量控制,确保了数据的准确性和可靠性,可为森林生态系统的健康评价提供数据支持。
Tianshan spruce(Picea schrenkiana var.tianschanica)is an important tree for water conservation,windbreak and sand fixation in the mountains of Xinjiang,and plays an important role in the formation and maintenance of forest ecosystem in Xinjiang.Ecological factors such as temperature,precipitation,soil and topography are important data bases for studying forest ecosystem.Based on multi-source data such as remote sensing image,DEM,meteorological data and soil data in Yili region of Xinjiang,we used multi-scale segmentation,nearest neighbor classification and spatial analysis to generate a dataset of ecological factors in the distribution area of Tianshan spruce in Yili region in 2014,covering six ecological factors,namely temperature,precipitation,sunshine duration,slope,slope direction and soil type.In this dataset,strict procedures of data quality control were carried out by TTA Mask accuracy verification and other methods to ensure the accuracy and reliability of the data.The dataset can provide data support for forest ecosystem health assessment.
