[目的
]
研究内蒙古自治区奈曼旗土地利用动态及生态系统服务功能与价值的演变情况,为该区土地的合理利用及生态治理工作提供科学依据。[方法
]
基于奈曼旗2000,2010与2018年土地利用数据,运用ArcGIS,Envi Classic计算土地利用动态度与土地利用转移矩阵,分析土地利用变化及生态系统服务的演变特征。[结果
]
①2000—2018年间奈曼旗呈“林地—水域—沙地”主导的土地类型演变特征,即林地、水域面积增加,沙地面积减少;其中林地面积净增312 100 hm

。②时间上,生态系统服务价值变化呈“一减一增”的趋势,其服务价值由2000年的3 050.7万元减至2010年的至1 991.58万元再增至2018年的4 728.55万元。③空间上,生态系统服务高值区、中值区与低值区分别位于南部、中部和北部,形成了“高—中—低”的区域分布格局。④生态系统服务功能上,气候调节的变化最为明显,其对应的服务价值由2000年的801.64万元增至2018年的1 349.85万元。[结论

2000—2018年间,研究区土地利用变化明显,其覆被结构明显优化,生态系统服务功能与服务价值也均提高。
[Objective] The dynamics of land use and the evolution of ecosystem service function and value in Naiman Banner of Inner Mongolia Autonomous Region were studied in order to provide a scientific basis for rational land use and ecological management in this area. [Methods] Based on the land use data of Naiman Banner in 2000
2010 and 2018
ArcGIS and Envi Classic software were used to calculate the land use dynamic attitude and land use transfer matrix
to analyze the evolution characteristics of land use change and ecosystem services. [Results] ①From 2000 to 2018
the evolution characteristics of land use type in Naiman Banner were dominated by “woodland-water area-sandy land”
that was
the woodland and water area was increased
while the sandy land area was decreased. The forest area increased 312 100 hm2
the water area increased 500 hm2
while the sand area decreased 142 100 hm2. ② In terms of time
the value of ecosystem services showed a trend of “decreasing and increasing”. The value of ecosystem services decreased from 30.507 million yuan in 2000 to 1.915 58 million yuan in 2010 and then increased to 47.285 5 million yuan in 2018. ③ Spatially
the high-value region
the middle-value region and the low-value region of ecosystem services were located in the south
the middle and the north respectively
forming a regional distribution pattern of “high-medium-low”. ④ In terms of ecosystem services
the change in climate regulation was the most obvious
the corresponding service value increased from 8.016 4 million yuan in 2000 to 13.498 5 million yuan in 2018. [Conclusion] From 2000 to 2018
the land use in the study area changed significantly
its cover structure was optimized significantly
and the ecosystem service function and value were also improved.
