摘要: 本文根据气候(主要为水热条件)、地貌、地质、土壤及植被等立地因素对杉木生长影响的研究,提出了杉木产区区划及立地分类系统。以水热条件和区地貌为依据,对杉木产区作出带、区(亚区)二级区划;在区(亚区)之下,以大地貌(岩性)、局部地形及土壤因素为依据,分别划分立地类型区(亚区),立地类型组及立地类型。同时还编制了杉木(实生)地位指数表和多因素数量化地位指数查定表,以评价立地生产力;对立地分类及立地评价在林场还作了应用研究。应用这个研究成果不仅可以避免目前有些地区不恰当地选择商品材基地和造林地,而且可以作为提出育林措施的依据,改善杉木林的栽培,提高杉木造林的生长、生态和经济效果。

Abstract: Aimed at improving silviculture practice of Cunninghamia lanceolata by providing a better understanding of site conditions,the present paper offers the recent research finding on systematic geographic regionalization and site classification based on systematic studies of climate (water,heat),topography,bed rock,soil and vegetations associated with chinese fir.3 zones and 5 regions are recognized,with special reference to climate and physiography. The regions are subdivided into subregions.Site types are grouped into groups and distincts based on mesorelief,microrelief (aspect,slope position), soil and vegetations.In addition,the site index table is prepared based upon tree hieght in definite age;another is besed upon relief and soils with method of multi-factor.The application of site classification and site quality evaluation are proposed for silviculture practice. Findings mentioned above provides guide lines for intensive cultivation of chinese fir.It is hoped to be useful to locating commercial production bases,choosing suitable sites and predicting productivity as well as handling silvicultural treatments with the purpose to raise the productivity of Chinese fir plantation.
