Comprehensive protection of urban environment usually results in the destruction of environment and ecology in town-and-country combining zone, which suffers from not only the agricultural environmental problem but also the destruction from urban industrial wastewater, solid waste and air pollution.

Town-and-Country combining zone is a transitional belt between urban and countryside, where environmental problems combine industry pollution with agricultural ecological destroying, showing distinctive particularity and complexity.

城乡结合带是城市与农村之间的一个过渡区带，环境问题集城市工业污染与农业生态破坏于一身，具有明显的特殊性和复杂性。
