Abstract：Based on three natural gas exploitation projects in Sulige field, this paper analyzed and compared proportions and areas of different land use types, and demonstrated different control measures on soil and water loss. Combined with lots of practice experiences, this paper also discussed the existing problems and obstacles in the current soil and water conservations for natural gas exploitation projects. The results demonstrated that: 1) the exploitation of natural gas project occupied many different land use types and on the whole, it can be divided into permanent and temporary land. Temporary land accounted for 75% of the total project area. 2) In the soil and water control areas, the area of pipe network and road was up to 90% of the total project area. Meanwhile, the two land uses contributed to 90% of the total amount of soil and water losses, being the vital areas for monitoring and controlling soil and water erosion. 3) The existing technical problems and obstacles in the current soil and water control measures were pointed out according to investigations and experiences. At the same time, corresponding suggestions were put forward as well.
