摘要
江西森林立地质量评价以杉木、马尾松为对象,以生态原理为基础,以地位指数为杠杆,以数学方法、计算机技术为手段,进行多角度、多指标、多方法的系统综合转换评价研究,将评价落实到地位指数、标准蓄积量、立地期望值、净现值等指标上,建立了森林立地质量评价系统,评价科学、系统、直观、实用。
Taking Chinese fir and Mason pine as objects,ecology theory as basis,site index as lever,mathematics as method,and computer technology as medium,this paper deals with the systematic and comprehensive translation evaluation of the forest site quality in JiangXi with multiangle,multiindexes,multimeans.The evaluation was put into effect to such indicatrixes as site index,normal volume, land expectation value,PNW etc.Thus,the evaluation system of forest site +quality is constructed.It has been proved to be scientific,systematic,audio- visal and practical.
