摘要：

为明确2010—2022年内蒙古大兴安岭森林植被净初级生产力NPP的时空变化特征及其对气候变化响应规律，基于MOD17A3H遥感数据与气象观测资料，采用趋势分析、偏相关分析法等方法，量化分析该区域森林NPP的时空演变格局及气候驱动效应。结果表明，内蒙古大兴安岭森林NPP年际变化呈现上升趋势，变化范围在331.04~456.45 gC/(m2∙a)之间，年变化呈上升趋势速率为12.7 gC/(m2·a)，空间上整体呈现“北高南低”的梯度递减格局，低值区集中于南部森林草原过渡带，高值区则位于北部林区。大兴安岭林区气温呈缓慢波动上升趋势，降水量呈缓慢波动下降趋势，两者空间分异显著且对NPP调控具有互补效应。偏相关系数空间分布表现为“南高北低”，其中降水是驱动林区NPP变化的主导因子。气温与降水的协同作用共同塑造了NPP时空分异格局。区域森林生态系统整体稳定向好，生态保护工程对生产力提升具有显著促进作用。研究结果可为内蒙古大兴安岭森林碳汇管理、生态保护修复及气候变化应对策略制定提供科学依据。

Abstract:

To clarify the spatiotemporal variation characteristics of forest net primary productivity (NPP) in the Greater Khingan Mountains of Inner Mongolia and its response patterns to climate change from 2010 to 2022, this paper quantitatively analyzed the spatiotemporal evolution pattern of forest NPP and the climate-driven effects in this region based on MOD17A3H remote sensing data and meteorological observation data, using methods including trend analysis and partial correlation analysis. The results showed that the interannual variation of forest NPP in the Greater Khingan Mountains of Inner Mongolia exhibited an upward trend, ranging from 331.04 to 456.45 gC/(m2·a), with an annual increasing rate of 12.7 gC/(m2·a). Spatially, it presented an overall decreasing pattern of “high in the north and low in the south”, and the low-value zones were concentrated in the southern forest-steppe ecotone. The air temperature in the Greater Khingan Mountains forest area showed a slowly fluctuating upward trend, while precipitation displayed a slowly fluctuating downward trend; both factors featured significant spatial heterogeneity and exerted complementary regulatory effects on NPP. The spatial distribution of partial correlation coefficients presented a pattern of “high in the south and low in the north”, with precipitation being the dominant factor driving NPP variation. Precipitation therefore acted as the dominant climatic factor for NPP changes in this forest zone, and the synergistic effect of air temperature and precipitation shaped the spatiotemporal differentiation pattern of NPP. The regional forest ecosystem was generally stable and improving, and ecological protection projects had a significant promoting effect on productivity enhancement. The findings can provide a scientific basis for forest carbon sink management, ecological protection and restoration, as well as the formulation of climate change response strategies in the Greater Khingan Mountains of Inner Mongolia.
