四川万岭菁楠竹林枯枝(死)状况与原因的研究

The State and Causes of Withered Moso Bamboo Groves on Wanlingqing Hills in Sichuan

四川省万岭菁楠竹林枯枝(死)状况是严重的。1987～1990年系统研究表明,楠竹林老年竹枯枝(死)主要是由经营因素导致的,占63.87％。虫害和病害是壮年竹株枯枝(死)的主要原因,占15.64％。 为了进一步验证楠竹林枯枝(死)的主要综合因子,采用多元回归和数量化理论(Ⅰ)方法,通过电子计算机运算。建立了多元回归予测方程和数量化理论(Ⅰ)予测模型,供生产应用。

The state of withered moso bamboo groves on Wanlingqin hills is heavy. Systematic researches from 1987 to 1990 showed that the withering of old bamboos in moso bamboo groves resulted mainly from poor management,making up 63. 87% ,while the main causes of the withering of robust bamboos were pests,occupying 15. 60% Multivariate regression analysis and quantification ( I ) method are adopted and computerized for the verification of major comprehensive factors resulting in the withering of moso bamboo groves. And the multivariate regression prediction equation,and the quantification ( I ) prediction model have been established for the use in production.
