2017-2020小兴安岭地区不同类型天然次生林下红松种源试验示范林数据集

本数据集针对小兴安岭地区，包括小兴安岭北部-丽林实验林场，小兴安岭中部-带岭林业实验局，小兴安岭南部-双丰林业局，收集了2017-2020年10种不同种源红松在不同地区、不同林型下的生长情况数据，包括：地径、树高、当年高和三年高等。数据以地区-林型为主要单元。数据集包含10个数据表，主要通过实地测量的方式进行数据采集

This dataset targets the Xiaoxing'an Mountains region, including three sub-areas: the northern Xiaoxing'an Mountains - Lilin Experimental Forest Farm, the central part - Dailing Forestry Experimental Bureau, and the southern part - Shuangfeng Forestry Bureau. It collects growth data of 10 provenances of Korean pine across different regions and forest types from 2017 to 2020. The collected indicators include ground diameter, tree height, current-year height, three-year height, and others. The dataset uses region-forest type as the primary statistical unit, contains 10 data tables, and all data were primarily collected via field measurements.
