摘要:

多种生态系统服务之间的相互关系研究是生态系统服务研究的热点问题。目前,有关多种生态系统服务权衡与协同的研究多停留在定性描述阶段,缺乏具备空间位置信息的定量研究。综合土地利用、NDVI、土壤类型、气象等多源数据,对汉江上游流域2000-2013年的土壤保持服务、产水服务、植被碳固定(NPP)服务进行空间制图,并基于逐像元偏相关的时空统计制图方法,对三种生态系统服务之间的权衡与协同关系时空变化进行分析。结果表明:① 2000-2013年,汉江上游多年平均土壤保持量为434.20 t·hm-2·yr-1,且多年来以16.10 t·hm-2·yr-1速率递增。多年平均产水量为250.34 mm,多年递增速率为3.79 mm·yr-1。NPP多年平均值为854.11 gC·m-2·yr-1,多年递减速率为8.54 gC·m-2·yr-1。② 汉江上游土壤保持量在空间上呈现出“南北山地高,河谷盆地低”的分布格局;植被NPP在空间上表现为汉江河谷地带低,其余地方高的态势;产水服务在空间上呈现由北向南递增的分布规律。③ 整个汉江上游流域土壤保持与NPP、土壤保持与产水服务均以权衡关系为主,权衡关系区域的面积占比分别达到62.77%和71.60%;NPP与产水服务以协同关系为主,协同关系的面积占比达到62.89%。④ 林地、湿地、耕地、人工表面及裸地中,土壤保持与NPP服务、土壤保持与产水服务在空间上以权衡关系为主,产水与NPP服务在空间上以协同关系为主;而草地表现为三种服务两两之间均以权衡关系为主。定量评估生态系统服务相互关系的时空特征,有利于研究生态系统服务之间相互关系在时间上的非线性变化以及空间上的分布异质性,对区域土地管理与生态系统服务优化具有重要的指导意义。

Abstract:

The research on the interactions among multiple ecosystem services (ES) is a hotspot. Most of the previous studies focused on the qualitative description of ES interactions, however, there have been relatively few studies on spatially explicit and quantitative assessment of ES interactions. In this paper, we mapped the ecosystem service of soil conservation (SC), net primary production (NPP) and water yield (WY) in the upper reaches of Hanjiang River Basin (URHR) based on the land use and land cover (LULC), NDVI, soil properties and observed climate data covering 2000-2013. Moreover, we quantitatively assessed the variation characteristics of interactions among different ES with a spatio-temporal statistical framework by applying the partial correlation analysis at a pixel scale. The results are shown as follows: (1) From 2000 to 2013, the mean annual SC was 434.20 t·hm-2·yr-1, and the mean annual WY was 250.34 mm. They also presented a rising tendency at the rate of 16.10 t·hm-2·yr-1 and 3.79 mm·yr-1, respectively. However, the mean annual NPP was 854.11 gC·m-2·yr-1, and presented a decreasing tendency at the rate of 8.54 gC·m-2·yr-1. (2) Spatially, SC was high in the North-South mountain area, while it was low in the Middle valley region. Similarly, the NPP in the Middle valley region was lower than that of other regions. However, the WY increased from north to south. (3) The three pairwise ES presented different interactions. Both the interaction between SC and NPP and that between SC and WY presented as trade-off, accounting for 62.77% and 71.60% of the total area, respectively. On the contrary, the interaction between NPP and WY was prone to synergies, accounting for 62.89% of the total area. (4) Pairwise ES in different land cover types also presented a different interaction. As for woodland, wetland, cropland, artificial land and bare land, SC and NPP, as well as SC and WY both presented trade-off, while WY and NPP presented synergy. Specially, in grassland, all the three pairwise ES presented a trade-off relationship. Therefore, spatially explicit and quantitative assessment of ES interactions are more helpful for revealing the temporal non-linear evolution, and the spatial heterogeneity of ES interactions. This analysis framework also contributes to the regional sustainable land management and the optimization of multiple ES conservation.
