在我国现阶段各类地图中,县挂图(以下简称县图)已成为能在较多方面与农业生产结合并直接为之服务和引起广泛注意与应用的最主要图种。随着科学的进步和农业的发展,无疑对县图的数量和质量将会提出更高的要求,对县图的内容、图型、科学性等又将产生重大影响。为了探讨我国县图编辑设计理论和有关技术规范问题,我们对十四个省(区)近期出版的一百五十余幅县图进行了阅读分析,结合我们多年来参与县图编绘的实践和体会,对我国县图发展的现状和趋势作一概略分析,对编辑设计工作提出几点改进意见。

In this paper a brief review has been made about the three periods of development of eotmty wall map making,and then analytical stresses are highlightedon the developing tendencies in 5 aspects:(1) The purposes of its productionbecome clearer daily.(2) The regional characteristics become more obvious.(3) The contents about quantity marks are increasing especially about agriculturalstatus.(4) Map making is developing from single map to series of maps.(5) Maps made by the joint efforts of concerning organizations of the province andthe county become more popular.Specialsubject maps based on the actual requirements of agricultural productionshould be mainly made in the future.Here we make our proposals for improvement in editing as follows:(1) Contents and informafions should be furtherenriched.(2) Regular mapping project should be established and its mathematicalaccuracy should be improved.(3) Proportion of maps for all subjects should beproper.(4) Standardization of the symbols in county maps should be graduallyrealized on the basis of the symbols used in the national graphical maps.(5) Remote sensing techniques should be more widely used so as to improve mapquality and speed up mapping processes.(6) Symbol for inhabited places ingeneral maps should be changed from a circle to plane outline for representation.
