摘 要：
对江西省抚河源自然保护区的水、光、热等主要气候因素变化特征进行分析,有助于全面了解并合理利用保护区的气候资源,为水资源利用、农业生产规划、生态环境监测等提供依据。基于广昌县1954-2017年气温、降水、日照时数等气候数据,利用一元线性回归、累积距平法、Mann-Kendall突变分析法,分析了该县近64年来气候特征;利用纽扣温湿度仪记录并分析抚河源自然保护区山地气候特征;使用NPP数据分析抚河源自然保护区植被NPP时空变化特征。结果表明:1954-2017年以来,抚河源自然保护区年平均气温为18.4℃,平均降水量为1 746.1 mm,年平均相对湿度为79.9%,年平均日照时数仅1 700 h,约占全年日照时数的38.41%;山地气候特征表现为气温随海拔升高而降低,而相对湿度随海拔升高而升高;抚河源自然保护区植被NPP随时间序列呈现减少的变化趋势。

摘 要：
The analysis of the characteristics of water, light and heat in Fuheyuan Nature Reserve in Jiangxi Province is helpful for the comprehensive understanding and rational use of the climate resources, and provides basis for water resources utilization, agricultural production planning and ecological environment monitoring. Based on climate data such as temperature, precipitation, and solar duration from 1954-2017 in Guangchang County, the climate characteristics of the city in the past 64 years were analyzed using linear regression, cumulative distance method, and Mann-Kendall method. The climatic characteristics of the mountainous area in Fuheyuan Nature Reserve were recorded and analyzed by the buttonedtemperature humidity meter. The spatial and temporal variation of vegetation NPP in Fuheyuan Nature Reserve was analyzed by using NPP. The results showed that since 1954-2017, the annual average temperature of Fuheyuan Nature Reserve was18.4 ℃, the average precipitation was 1 746.1 mm, the average annual relative humidity was 79.9%, and the average annual solar duration was only 1 700 h, accounting for approximately 38.41% of the annual allowable hours; The climate characteristics of mountainous areas are that the temperature decreases with elevation and the relative humidity increases with elevation. NPP vegetation in Fuheyuan nature reserve showed a decreasing trend with time series.
