<正>利用地物光谱仪研究了太湖DOC浓度与反射光谱之间的关系，结果表明：DOC浓度与745nm附近的反射率及665、695nm处一阶微分具有较好的相关性，可以用745nm处反射率及665、695nm处一阶微分来估算DOC浓度。通过对模拟MERIS数据的分析，得出太湖的DOC浓度也可以用MERIS的第i0，aa及第9波段与12波段的比值有效地估测。

The heredity variability of the height, diameter and volume growth, interaction effect of biomass and circumstance of 6~7 years old Fokienia hodginsii plantation including 17 geographical provenances and 48 families in Hunan province were studied. The results indicated that there were obvious differences in the height, diameter and volume growth at mountain, middle mountain and hill. Heritability of the height, diameter and volume is 0. 5561~0. 903 4, 0.630 3~0.9140, 0.670 1~0.914 3 respectively. Between the provenances and environment of interaction, the rank of the height, diameter and volume growth was mountain>middle mountain area>hill. Based on the selection standard on the volume growth exceeded (15%) of average provenances, 7 superior provenances and 16 families were tentatively selected with the genetic gain of 18.99~94.96%, 16.78~215.75% respectively. Based on the selection standard on the volume growth exceeded of average provenances, 99 superior provenance plus trees and 140 families plus trees were tentatively selected with the genetic gain of 63.66%~257.61G, 138.33%~878. 340//oo respectively.
