摘要

[目的

]

准确了解2010年以来扎龙自然保护区生态变化，为提高湿地生态系统服务价值评估能力提供数据支持和理论参考。[方法

]

基于遥感、气象、地面协同观测数据，利用CASA (Carnegie-Ames-Stanford Approach)模型、GSMSR (Geostatistical Model of Soil Respiration)模型和回归分析等统计方法，分析气候变化对2010—2020年扎龙自然保护区土地覆盖、植被生态质量、净生态系统生产力(NEP)等的影响。[结果

]

①扎龙自然保护区的主要土地覆盖类型为有水草甸，占保护区面积的37.24%，主要分布在核心区，但面积总体呈下降趋势； ②植被覆盖度呈波动增长趋势，年最高植被覆盖度平均为74.62%； ③植被生态质量指数呈增加趋势，2019，2020年处于“好”等级；NEP平均为253.59 g/(m

·a)(以C计)，呈现东高西低的空间分布特征； ④生长季平均固碳量为5.69×10

t/a，释氧量1.52×10

t/a，均存在上升趋势； ⑤气温对生态监测指标的影响大于降水量。[结论

扎龙自然保护区是嫩江流域生态最为脆弱的区域，植被生产力受气候影响大，需要加强生态保护和修复。

Abstract

[Objective] The ecological changes in Zhalong Nature Reserve since 2010 were studied accurately in order to provide data support and theoretical references for improving the ability to assess the value of wetland ecosystem services. [Methods] Based on remote sensing

meteorology

and ground-based observation data

the impacts of climate change on land cover

vegetation ecological quality

and net ecological productivity in Zhalong Nature Reserve were analyzed using the Carnegie-Ames-Stanford Approach (CASA) model

the Geostatistical Model of Soil Respiration (GSMSR) model

regression analysis

and other statistical methods. [Results] ① The main land cover type in Zhalong Nature Reserve was a water-bearing meadow

which accounted for 37.24% of the total area of the reserve

and was mainly located in the core area. This land cover type showed a downward trend over time in the area. ② Vegetation coverage showed a fluctuating growth pattern

with annual maximum vegetation coverage of 74.26%. ③ The vegetation ecological quality index showed an increasing trend and was characterized as being in the good level in 2019 and 2020. The average net ecological productivity (NEP) was 253.59 g/(m2·yr) (calculated in C)

and showed a spatial distribution pattern of higher in the east and lower in the west. ④ The average carbon fixation during the growing season was 5.694×105 tons/yr

and the oxygen release was 1.517×106 tons/yr

both of which showed upward trends. ⑤ The impacts of air temperature on ecological monitoring indicators were greater than the impacts of precipitation. [Conclusion] Zhalong Nature Reserve is the most ecologically fragile area in Nenjiang River basin

and its vegetation productivity is greatly affected by climate. Therefore

it is necessary to strengthen ecological protection and restoration.
