为了科学地评价福建省宜林地立地质量等级和生产潜力，选取福建省顺昌县81块杉木标准地，基于模糊综合评价法与数量化理论法确定立地质量等级并构建数量化理论预测方程，从分级与数量化两方面分别进行评价与模拟。结果表明：研究区立地综合得分值为1．701，立地等级为中级；影响杉木宜林地立地质量的因子重要性依次为土层厚度、坡向、腐殖质厚度、地貌、海拔、土壤类型、坡度、坡位，并定量地给出各立地因子对林木生长的贡献。两种方法经检验均达到理想效果，可作为评价宜林地立地质量和预测造林后林木生长趋势的有效方法。

To scientifically evaluate the site quality grade and potential productivity for the suitable land for forest of Fujian Prov -ince, we determined the site quality grade and establish prediction equation of the quantification theory based on the fuzzy comprehensive evaluation and quantification theory in 81 sample plots in the Chinese fir on Shunchang County of Fujian Province.The evaluation and simulation were conducted for the site quality from two aspects of grading and quantification . The comprehensive evaluation score was 1.701 and the site quality grade was middle rank .The order of importance affecting the site quality for the suitable land for Chinese fir forest as follow:soil thickness, exposure, humus depth, landform, ele-vation, soil type, slope and slope position.Then, we quantificationally calculated the contributions to the trees growth for all the site factors.Two methods reached the ideal effect by the test , which can be used as the site quality evaluation and prediction in forest growth tendency after the afforestation for the suitable land for forest .
