Estuarine and catchment characteristics.

Data obtained from the New Zealand Estuarine Environment Classification Database [35].Estuarine water area at high tide and land catchment area in km2. Shore length in km. The shore complexity index (SC) as the length of the perimeter of the estuary shoreline divided by the circumference of a circle that has the same area as the estuary (1 simple and 2). Mean tide range in metres. Intertidal, as the percentage of intertidal area in the estuary at high water. Land-use variables based on the percentage of catchment covered by natural, pastoral and exotic vegetation and urban areas.

本数据集的数据来源于新西兰河口环境分类数据库（New Zealand Estuarine Environment Classification Database）[35]。包含以下参数：高潮状态下的河口水域面积与集水陆域面积，单位为平方千米；岸线长度，单位为千米；岸线复杂度指数（Shore Complexity, SC）：以河口岸线周长除以与河口面积相等的圆形的周长计算得到，取值范围为1（代表岸线形态最简）至2（代表岸线形态最复杂）；平均潮差，单位为米；潮间带占比：高潮时河口潮间带面积占总河口面积的百分比；土地利用变量：基于集水区内自然植被、牧场植被、外来植被以及城市用地的覆盖占比计算得到。
