摘要：西南喀斯特山区贫困乡村属我国生态脆弱的集中连片特困区,其生态系统服务水平对贫困乡村的社会经济可持续发展至关重要。基于2018年遥感解译数据,采用价值当量换算法,在ArcGIS软件支持下,比较了我国西南喀斯特地区的喀斯特中山(石门乡)、峰丛洼地(宗地镇)、峰丛峡谷(掌布镇)、低山丘陵(周覃镇)4个不同地貌类型的贫困乡村生态系统服务价值。结果表明:(1)峰丛峡谷的掌布镇和峰丛洼地的宗地镇单位面积生态系统服务价值高于喀斯特中山的石门乡和低山丘陵地貌的周覃镇。调节服务价值在4种地貌乡镇的服务类型中均占主导地位;(2)掌布镇和宗地镇的单位面积生态系统服务价值高值区和低值区均呈现集中分布特点,而石门乡和周覃镇则呈分散分布为主;(3)随地形位指数的增加,不同地貌乡镇的单位面积调节服务、支持服务、文化服务及总服务价值逐渐增加,而除周覃镇外,其他地貌乡镇的供给服务价值在地形位梯度上变化不突出。
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 in2018,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.
