Spatial Pattern Analysis on Water Conservative Functionality of Land Ecosystem in Northern Slope of Qinling Mountains
[Objective] Analysis on spatial pattern of water conservative functionality of land ecosystem in the northern slope of Qinling Mountains to provide scientific reference for water resources planning and management
and balancing water resources allocation and urban economic development. [Methods] This paper analyzed the water conservation ability and the spatial heterogeneous pattern of the northern slope of Qinling Mountain at watershed scale in 2000 and 2010. Based on InVEST model
the influence factors of water conservation capacity were analyzed. [Results] (1) In 2000
the amount of water conservation in the northern slope of Qinling Mountains was 4.02×109 m3
superficial 242.37 mm in an average. In 2010
the amount of water conservation in the northern slope of Qinling Mountain was 4.45×109 m3
superficial 265.33 mm in an average. (2) The main water retention area in the northern slope of Qinling Mountain are Heihe River
Shitou River
Chanhe River and Bahe River basin. Their high value areas of water retention function located at some sub-watersheds
correspondingly as the souths of Heihe River
Shitou River
Shensha River and Bahe River. (3) Climate factor was found closely related to the ability of water conservation. Through the effect of vegetation change
land use/cover affected the regional water conservation function. For vegetation types
deciduous broad-leaved forest contributed the most proportion; for soil properties
brown soil had the highest contribution rate. [Conclusion] Water conservation capacity varied differently with regions by its comprehensive factors
such as climates
the way of land use
vegetation cover and soil conditions. In a word
the closer to the main ridge of Qinling Mountains
the stronger ability of water conservation in the northern slop of Qinling Mountains.
