摘 要: | 本研究以豫西伏牛山区104块日本落叶松人工林标准地优势木平均树高作为研究材料,拟合三个数学模型,最后选定用模型IgH=0.0792 0.8880IgA编制地位指数表,基准年龄为26年,用变异系数导出16、18、20、22、24、26、28七条地位指数曲线.经相关系数检验表明:该地位指数表适用于豫西伏牛山区日本落叶松人工林。

Site index table of Japanses Larch artificial protection forest for water conservation in Henan west funiu mountains |

Abstract: | Based on the date of the dominant trees' height from 104 Japanese Larch plantation sample plots of the west mountain areas of Henan Funiu mountain were used to develop site index table based on mode lgH=(0.0792)+0.8880lgA. The standard age was 26a, and 16,18,20,22,24,26,28 sever site index curves were derived with method of coefficient of variability. The results of correlation coefficient test indicated that the site index table is suitable for Japanese Larch artificial protection forest for water conservation in the area the date came from. |
