【摘要】 白蚁是城市中极其重要的害虫，为害对象广泛，十分严重。本文阐述了城市发展和城市生态系统的特点。城市化进程对白蚁种群变化的影响──①原有大、中型城市建设逐步发展，一些外来种的白蚁．如小楹白蚁Incisitermesminor（Hagen）和侧角楹白蚁I.laterangularisHan由国外传入。②新兴城市发展淘汰了依赖山林的白蚁，而适应性强的白蚁类群得以生存和发展。③Coptotermes分布北界附近的城市，受气候因子的限制，种群数量小，用“灭蚊灵”灭治，即可较长时间控制。城市建设对白蚁生存、发展有不利的一面．也有有利的一面。①城区园林绿地扩大，花木增多对白蚁生存、发展极为有利，很多大树常有Coptotermes的树巢。②水运方便的城市，码头灯光照明为Coptotermes分飞建巢提供了有利条件。③城区水泥、沥青路面大量增加对Reticulitermes和Coptotermes分群落巢建群不利。更多还原

【Abstract】 Termites are important pests of cities, they cause extensive and serious damages. This paper reviews:1. The features of city development. city ecosystem, and the effect of citifying process on population changes of termites:(1)With the development of construction, some foreign species such as, Incisitermes minor (Hagen ) and I. laterangularis Han were introduced into the former large and mid cities.(2) With the development of new cities, wood dwelling termites are eliminated, fut the termites with stronge adaptability may survive and develop.(3)Coptotermes may be controlled by Mirex (C10Cl2 )in cities which near the north limit of its distribution. because that limited by the weather and other facts, the population of coptotermes in these cities is small.2. The effect of city construction on survival, development and harm of termites: (1) Modern reinforced concrete building are both advantageous and disadvantageous to the survival and development of termites.(2) The afforestation in cities favors termites, Coptotermes often nest inside large trees.(3)Cities which have water transhort condition , the light of ports may favor the swarming of Coptotermes.(4)The increase of cement and bituminous road disadvantages the nest construction of Reticulitermes and Coptotermes.更多还原
