紫金山彩红外片马尾松数量化立地指数表的编制

Tabulation of Quanti-fication Color Infrared Aerial Photo Site-Index for Pinus massoniana in Mt. Zijin.

运用数量化理论Ⅰ混合模型，在彩红外片上判读立地因子，并实测马尾松优势木高，编成紫金山彩红外片马尾松数量化立地指数表。该表经验证，精度较高，预测可靠，可应用于生产实际。立地因子分析表明，土壤有效厚度、坡向和坡位可作为紫金山林区划分立地类型评定立地质量的主导因子。

With the mixed model in the quantification theory Ⅰ,a table ofquantification color infrared aerial photo site-index for Pinus massoniana inMt,Zijin, Nanjing,was tabulated by interpreting site factors on colorinfrared aerial photo.By testing of t-value and error analysis,the resultsshowed that the factors which played a leading role were effective soil depth,aspect and hill place, and that the table had a high precision and waseffective to forest site classification and appraisal.
