森林资源连续清查森林资源连续清查continuous inventory of forest resources senljn ziyuan lianxu qingeho森林资源连续清查(continuous invent卿of forestre-sources)定期对同一对象重复进行可对比的森林调查。通常是以数理统计连续抽样技术和固定样地为基础进行资源调查，主要目的是了解资源的动态变化，用来评价一定时期内人为活动对森林资源的影响，为制定林业发展规划和方针、政策和预测森林资源的发展趋势提供科学依据。 森林连续清查适应于较大地域的控制性调查。通常在同等精度下，地域愈大，其抽样效率愈高。要求每次重复调查都在大体相同的时间进行，且以在非生长季调查为宜。 森林资源连续清查适用于较大区域范围的宏观性资源调查。北欧国家于20年代即开始了全国性森林资源连续清查。中国从1975年开始以省为单位进行了这一工作，到1981年，全国除上海、西藏、台湾省外，先后均完成了以省(区、市)为单位的森林资源连续清查工作。随后各省(区、市)已分别于198刁~1988年和1989~1993年完成了第一、第二次复查，及时提供了全国及各省(区、市)森林资源现状与消长动态，为林业决策提供了科学依据。从1994年开始，全国进行第三次复查。按5年间隔期复查一次，即平均每年对全国l/5省(区、市)开展复查工作，并形成制度。同时在调查范围、内容，技术手段等方面都有了改进和提高，从而使全国森林资源连续清查体系的建设更趋完善。 调查步骤分固定样地设置、样地外业调查及内业计算与分析等。首先按照资源状态确定样地面积和数量，然后布设样地;连续清查样地一般可布设在地形图的公里网交叉点上。在野外按设计图上标定的位置设置和调查样地。样地调查内容包括样地的坡度、坡向、海拔、林龄、郁闭度等情况的记载;样木胸径、树高的测定，并进行土壤、更新与病虫害等调查。内业计算与分析主要依据野外资料，采用数理统计方法按总体计算各种估计值和抽样误差，分析调查间隔期内森林的生长与消耗量及资源的变化，撰写森林资源报告和编制有关图表等。 (李飞袁运昌)
