Abstract：In the karst environment, the urban ecosystem, vulnerable in nature and with extremely limited load capacity can hardly sustain any negative interference and behaviors from hum an being s. Thus, it is easier to destroy the urban ecosystem, but much more difficult to restore it. Taking nine cities for example and from the view points of urban natural environment and influence from man's activities, this paper studies problems of ecological environment in cities of Guizhou and counter-measures of coordinating problems of man-land in cities. This paper consists of three parts as follow s:(1) Features of natural environment in cities of Guizhou. Guizhou is known as a ‘karst province’, for nearly all the cities and towns are located in karst areas. The karst environment restricts the formation and construction of the cities, water and land resources and urban expansion. In such circumstances, the ecological system is very vulnerable. The nine cities mentioned are surrounded with K-shaped, isolated hills or enveloped landform. The mountainous and hilly areas take over 72 percent in area. Thus, with scarcity of land resources, land use is greatly limited.(2) Problems of urban ecological environment. Ascribed to such factors as underdevelopment of science and technology, economy and urban management, a lack of awareness of environmental protection, release of tri-type of wastes mostly without being tackled, the naturally vulnerable karst environment in addition, there arise severe urban environmental problems:mainly the problems of air pollution from coal-burning, water pollution from organism and noise pollution from traffic.(3) General counter-measures for reconstruction of urban ecological environment. The government's leading role should be strengthened;environmental protectionshould be legislated, and urban natural surroundings should be exploited so that the cities will be built into ones with mountains and waters. Some specific measures are proposed as follow s:first, establishing forceful organizations and legislations for environmental protection;second, enforcing management and protection of water environment;third, building up an urban green land system;fourth, developing urban eco-tourism and suburban eco-agriculture.
