Wetland Functional Area Division Method: A Correlation Analysis of Water Quality and Landscape Structure

The purpose of this study is to provide a clearer idea for the optimization wetland functional areas and new method identification analysis under background latest Wetland Protection Law in China. This selected Pan’an Lake Wetland, first national park built coal mining subsidence land China, as research object. By constructing “Water-water-landscape-function” (WLF) model, combined with landscape pattern index Nemerov pollution (NPI), differences water quality structure different were analyzed. Then, Pearson’s Correlation Analysis Redundancy are quantitatively analyze correlation between environment structure. Finally, Inverse Distance Weighting (IDW) was introduced help spatial difference areas. lasted one year. Twelve sampling points set up, 216 effective samples collected monthly results showed that: (1) ratio built-up cultivated area had high impact on indicators each period, especially increase patch density would risk TN TP losing surrounding bodies; (2) lakes rivers have good ecological effects should be widely used various areas; (3) degree fragmentation negatively correlated overall quality, while agglomeration diversity positively quality; (4) corridors established WCA WRA, artificial MEA LEA, interception WRA; (5) “Water-quality-landscape-function” model an tool areas, which provides reference round planning
