The construction of ChinaPakistan Economic Corridor(CPEC), as an important part of “The Belt and Road Initiative” strategy is of great significance. However, environmental risk in the construction process of CPEC cannot be neglected. The paper analyzes resource environment characteristics of Pakistan from the perspective of atmospheric environment, water and soil resource constraints, biodiversity and forest resource constraints. Then, it is pointed out that the main resource environment problems of Pakistan include extreme shortage of water resource, low percentage of forest cover, soil erosion and degradation and damage of biodiversity. Based on the spatial characteristics of corridor ecology environment factors and economic development situation, it analyzes the main environmental risk of corridor construction investment and makes suggestions to mitigate environment risk.
