摘要

[目的

]

揭示罗山保护区植被净初级生产力（NPP）变化规律及气候相关性，为宁夏回族自治区及其周边生态环境保护提供科学依据。[方法

]

利用MOD17A3H NPP（2004—2015年）数据、SRTM DEM和罗山周边气象站点（2004—2015年）年均气温和降水数据，运用相关性分析、趋势分析、线性回归分析等方法，分析气候、人口、生态及移民政策等对研究区植被净初级生产力的影响，对区内NPP时空变化特征进行定量化分析。[结果

]

①研究区内植被净初级生产力的变化与降水的相关性较高；在核心区，降水与NPP的相关系数R=0.609，置信度p=0.036；在非核心区，相关系数R=0.648，置信度p=0.023；②研究区NPP呈波动增长趋势，速率为0.076 Pg/a（以C计），高于全国NPP增长速率（0.008 Pg/a）； ③2010—2015年大罗山森林覆盖面积有所增长，NPP介于350～500 g/（m

·a）的森林面积是2004—2009年的4倍，小罗山方向基带植被由荒漠向荒漠草原转化； ④研究区以NPP划分的生态格局主要以荒漠为主（64.9%），荒漠草原次之（29.6%），森林占比极低（0.38%）。[结论

]

干旱区植被NPP高度依赖降水，罗山地区生态结构有所改善，但森林生态系统仍极端脆弱。

Abstract

[Objective] The net primary productivity(NPP) change and its correlation with climate over the Luoshan nature reserve were investigated in order to provide scientific basis for the ecological environment protection in Ningxia Hui Autonomous Region and its surrounding areas.[Methods] Based on the data including MOD17A3H NPP from 2004 to 2015

SRTM DEM

and annual average temperature and precipitation

and the methods including correlation analysis

trend analysis

and linear regression analysis

this study analyzed the spatiotemporal change characteristics of the NPP and the effects of climate

population

ecology

and immigration policy on the NPP.[Results] ① There had a high correlation between the NPP and annual precipitation with correlation coefficients equaling to 0.609 and 0.648(p<0.05) in the core and non-core areas

respectively; ② The NPP represented a fluctuating increasing trend with 0.076 Pg/a over the entire study area

which is higher than the NPP trend with 0.008 Pg/a over the China; ③ The forest area increased during 2010-2015 in the Daluoshan and the area of forest with NPP ranging from 350 to 500 g/(m2·a) was 4 times of that during 2004-2009; Baseline vegetation in the Xiaoluoshan was converted from desert to desert grassland; ④ The dominated ecological pattern determined by the NPP was the desert with area percent of 64.9%

followed by the desert grassland with 29.6% and the forestland with 0.38%.[Conclusion] The NPP of arid area is highly dependent on the precipitation. Although the ecological structure of the Luoshan region has been improved

the forest ecosystem there is still extremely fragile.
