摘要： Facility agriculture is an important mode of development in modern agriculture, and it played a key role in improving the ecological function. Based on the descriptions on ecological function of modern agriculture, a number of ecological and environmental problems caused by large-scale facility agriculture were analyzed in this paper. Agricultural facilities tent membrane change surface coverage types of facilities agriculture area, will cause changes in the rate of surface occurs and break the original surface energy balance. Facilities agriculture covered by insulation in the night will prevent the surface heat from diffusing and reduce the absorption of long-wave radiation. The covered tent membrane barriered vapour from exchanging and reduce total plant evapotranspiration. The change of environments inside of the agricultural facilities will influence the balance of the soil respiration. The unreasonable cultivation practices will destroy regional soil quality. These environmental problems will weaken the urban ecological conservation in modern agriculture. Accordingly, we put forward corresponding countermeasures and Suggestions.
