陕西河谷盆地是区域主要粮食基地和社会经济中心,人口增长、城镇化和工业化的加快发展,使得该地区生态环境受到人类活动的强烈冲击,生态环境面临着潜在的巨大危机,严重影响社会经济的可持续发展。本文选取西北地区经济中心—关中盆地和陕西省生态保护指定区—汉中盆地进行对比研究,以1990-2010年的生态系统服务数据(NPP、保水服务、食物供给)分析生态服务时空差异,通过相关分析、线性和幂函数回归等方法分析了生态系统服务协同与权衡的时空差异。结果表明:NPP与保水是协同关系,NPP与食物供给、保水与食物供给是权衡关系;21年中,两大盆地的协同关系均呈减弱趋势,权衡关系为加强趋势,且关中盆地的变化速度要高于汉中盆地;NPP与保水的协同程度,在关中盆地东部的耕地区域以及汉中盆地的宁强县与略阳县西部最强,以关中的铜川市和汉中的西乡县最弱;NPP与食物供给的权衡程度,在关中盆地的铜川市和西安市境内的秦岭区域以及汉中盆地的西乡县南部制约关系更为突出,以关中的宝鸡市及汉中的略阳县最弱。 |

The valley basins, the main grain output area and socio-economic center of Shaanxi Province, are experiencing population growth, rapid urbanization and industrialization. However, the eco-environment is suffering as a result of destructive human economic activities(forest and grassland clearance for farmland expansion, deforestation and vegetation damage) and is potentially facing a huge ecosystem crisis, from the likes of soil erosion and vegetation coverage reduction-all of which hinder local sustainable social and economic development. Because of complicated conditions and its significant location, the Guanzhong Basin, the economic center of Northwest China, and the Hanzhong Basin, an ecological preservation area in Shaanxi Province, were chosen for comparing and analyzing the spatial and temporal disparities between ecosystem services. In this study, we use several mathematical methods including the correlational analysis method, and the linear and power function regression methods to calculate the spatial and temporal differences between the two areas based on ecosystem services data from 1990 to 2010 (NPP, water conservation and food supply). From this, we find that NPP and water conservation have a synergistic relationship, and that there is also a trade-off between NPP and food supply, and between water conservation and food supply. In addition, between 1990 and 2010, this synergistic relationship shows a downward trend while the trade-off relationship demonstrates an upward trend. Furthermore, the rate of change in the Guanzhong Basin is faster than that in the Hanzhong Basin. In terms of the synergistic relationship between NPP and water conservation, the strongest evidence can be found in cultivated land in the east of the Guanzhong Basin and in the west of Ningqiang county and Lueyang county in the Hanzhong Basin; the lowest is observed in Tongchuan city and Xixiang city. When exploring the trade-off between NPP and food supply, we find that the strongest trade-off relationship is in Tongchuan city and the Qinling Mountains in Xi'an and the south of Xixiang county, while the weakest is in Baoji city and Lueyang county. |
