The poverty-stricken villages in southwest karst mountainous areas are concentrated and contiguous poverty-stricken areas with fragile ecology in China, and their ecosystem service level is very important for the sustainable development of social economy in poverty-stricken villages. Based on the remote sensing interpretation data in 2018, ecosystem services value in Karst Mid-mountain（Shimen）, Peak cluster depression（Zongdi）, Peak cluster canyon（Zhangbu） and hilly area（Zhouqin） were compared by the method of value equivalent conversion with the help of ArcGIS software. The results showed that:（1） Ecosystem services value per unit area in Zhangbu with peak cluster canyon and Zongdi with peak cluster depression were higher than Shimen with Karst mid-mountain and Zhouqin with hilly area. The adjustment service value is dominant in the service types of the four landform towns.（2） The high and low value areas of ecosystem service value per unit area of Zhangbu and Zongdi are centralized distribution, while Shimen township and Zhouqin town are mainly distributed.（3） With the increase of terrain niche index, the value per unit area of regulating service, supporting service, cultural service and total service in four towns with different landforms gradually increased. Except Zhouqin Town, the supply and service value of other geomorphic towns did not change significantly in the topographic gradient.
