Water environmental capacity is an important factor in total pollutant control and water environmental management. Due to the uncertainty of the water environment, the uncertainty analysis of water environmental capacity is crucial. Most uncertainty analyses of water environmental capacity do not consider the correlation between various parameters that were used to calculate water environmental capacity. In this study, the copula model of discharge and water quality was constructed to analyze the uncertainty of water environmental capacity. The risk threshold of each river section was calculated when the water environmental capacity was less than 0 in the wet, normal and dry seasons. The Yitong River Basin in Changchun city was taken as a case study. The results showed that the 68.27% confidence level was considered to reduce the uncertainty of water environmental capacity by more than 54.90%. The uncertainty of water environmental capacity in the wet season was the largest, and the risk threshold was the smallest. The risk thresholds for the water environmental capacity of each river reach were all greater than 90% in the dry season. The method of this study can be extended to other basins for uncertainty analysis of water environmental capacity.

Ecological science focuses on the structure and function of the natural environment. However, the study of ecological environments primarily focuses on single-element research and lacks a comprehensive perspective. To examine ecological environmental trends on different scales, the present paper selected Yunnan Province as the study area. Chemical oxygen demand, rocky desertification, forest coverage, natural disaster data and spatial analysis methods were used to obtain the ecological environmental characteristics of each county and construct a comprehensive evaluation method of the ecological environment. The present paper revealed that the environmental capacity in Yunnan Province was at a moderate level, the ecological environment fragility was remarkable, the significance of the ecological environment was very high, natural disasters occurred frequently, and spatial differentiation between ecological environments was obvious. The province may be divided into three functional areas: the comprehensive-balanced area, the efficiency-dominated area and the environment-dominated area. Central Yunnan was a key development zone and the main area for the manufacturing and service industries, which were built as a modern industrial system in Yunnan Province. The ecological environment in northwestern Yunnan and southern Yunnan is of high significance, and this region was an ecological environment protection area that was important area for the construction of the modern agricultural system in Yunnan Province. To achieve sustainable development of the ecological environment, the spatial characteristics of the ecological environment must be determined at the county scale.
