水体空间分布多样性的提出为地表水资源的分布特征评价提供了一种新的思路和方法.网格尺度设置是其研究结论获取的前提条件。以河南省内5个典型样区为例,计算了1:4种不同网格尺度下水体空间分布多样性的变化特征,以期探索水体空间分布多样性研究中合理网格尺度的设置准则。结果表明,水体空间分布多样性研究中的网格尺度设置为2kin~500m之间为宜。
The water spatial distribution diversity provides a new idea and method for the evaluation of surface water distribution, and the grid scale setting is the prerequisite for its research conclusions. Five typical case areas in Henan Province were selected for a variation analysis of water spatial distribution diversity in 14 different grid scales to explore the setting strategy of proper grid scale in the water spatial distribution diversity study. Results show that the best grid scale in the water spatial distribution diversity is between 2km to 500m.
