中文摘要: |
基于山东省第一次到第九次森林资源清查数据以及气象数据,研究山东省森林资源质量变化及其与年均温的关系。结果表明,山东省乔木林面积、蓄积量、单位面积蓄积量、单位面积生长量、单位面积株数、平均胸径均呈逐渐升高的变化趋势,但各项指标均低于全国平均水平;乔木林蓄积、单位面积蓄积量和平均胸径均与年均温呈显著正相关,用材林和防护林单位面积蓄积量与年均温呈显著正相关,人工林平均胸径与年均温呈显著正相关。山东省森林资源质量稳步提高,气温对山东省森林资源质量的提升具有积极的作用。 |
英文摘要: |
The first to ninth forest resources inventory and meteorological data of Shandong Province were used to study the variation of forest resources quality and its relation to average annual temperature in Shandong Province. The results showed that the area, volume, volume per unit area, growth per unit area, number of trees per unit area and average diameter at breast height of arbor forest in Shandong Province showed a gradually increasing trend, but those indicators were lower than the national average. In addition, the volume of arbor forest, volume per unit area and average diameter at breast height were significantly positively correlated with the average annual temperature, respectively. Moreover, the volume per unit area of timber forest and shelter forest showed positive linear dependence upon the average annual temperature, and the average diameter at breast height of plantation was significantly positively correlated with the average annual temperature. In a word, the quality of forest resources in Shandong Province has improved steadily, and the temperature plays a positive role in improving the quality of forest resources in Shandong Province. |
