| 摘 要： | 以浙江省为例,探讨了省域大比例尺土壤数据库的构建方法,并结合第二次土壤普查资料,建立了浙江省1∶5万大比例尺土壤数据库,包括空间数据库、属性数据库和元数据三部分。自主研发的土壤界线自动识别和半自动识别技术的采用,显著提高了土壤图数字化的精度与效率;土壤数据库标准的制定保证了数据库建设的规范、有序;参考地形图、遥感影像等信息,对土壤图图面错误进行了拓扑学和土壤学修正,解决了原图中存在的土壤界线遗漏、界线不连续、图斑注记缺失等问题,显著提高了土壤图的质量;对县、区土壤普查分类、省普查汇总分类及国家标准分类的归属关系进行了整理,解决了原普查成果存在的"同土异名"和"异土同名"问题。建立的浙江省土壤空间数据库共划分156 581个土壤图斑,搜集整理土壤剖面2 677个,实现了全省土壤图的无缝拼接、空间与属性数据的关联,在一定程度上奠定了浙江省"数字土壤"的基础。此外,对已有研究成果的不足进行了讨论,指出了其改进的方向,期望在完善浙江省大比例尺土壤数据库的同时,也为其他省区的大比例尺土壤数据库构建工作提供参考。

| Abstract: | With the aim of exploring and conserving soil resources, and promoting soil science, China conducted the second nation-wide soil survey in 1979, and has made substantial achievements out of the survey. To make better use of the results and also to keep abreast of the development in science and technology, constructing a soil database became an urgent task. After ten years of joint efforts, a soil database for Zhejiang Province was completed, encompassing 1:50 000 digitized soil maps for all the counties of the Province and consisting of three sections, i.e. spatial data, attribute data and meta data. The use of the techniques of automatic and semi-automatic soil boundary recognition developed through independent R |
