纳帕海湿地明水水面和水量波动数据集（1990-2011）

纳帕海湿地被列入国际重要湿地名录，编号1440号。在1990-2011年48期纳帕海湿地Landsat TM/ETM 遥感数据、2011年11-12月GNSS（Global Navigation Satellites System）RTK（Real Time Kinematic）数据基础上，利用修正的归一化水指数模型（mNDWI）；得到纳帕海湿地48期明水面空间分布和面积数据。利用1988-2011年研究区逐日降水数据，建立降水与明水面积关联模型，进而计算得出纳帕海湿地水量波动数据集。数据集包括地理信息系统空间数据和统计数据两种类型。空间数据包括：（1）2011年12月12日完成的纳帕海湿地明水景观实际测量边界数据；（2）1990-2011年48期Landsat ETM 影像提取的纳帕海湿地明水面空间分布信息。统计数据包括：（1）1990年5月-2011年8月纳帕海湿地的明水面积和最佳累计日降水量数据；（2）1988年-2011年纳帕海湿地每月平均的明水水量数据；（3）纳帕海湿地多年月平均明水水量与多年月均降水量数据。该数据集存储为.mdb、.gdb和.xlsx格式，数据压缩为792KB。该数据集的分析研究成果发表在《自然资源学报》2015年30卷第2期。

Napahai Wetland has been inscribed in the List of Wetlands of International Importance with the serial number 1440.
Based on 48 scenes of Landsat TM/ETM remote sensing data of Napahai Wetland from 1990 to 2011 and GNSS (Global Navigation Satellite System) RTK (Real Time Kinematic) data collected from November to December 2011, the modified normalized difference water index (mNDWI) model was applied to derive the spatial distribution and area data of open water bodies in 48 scenes of Napahai Wetland.
Using the daily precipitation data of the study area from 1988 to 2011, a correlation model between precipitation and open water area was established, and the water fluctuation dataset of Napahai Wetland was further calculated.
This dataset contains two categories of data: geographic information system (GIS) spatial data and statistical data.
The spatial data includes: (1) Actual measured boundary data of the open water landscape of Napahai Wetland completed on December 12, 2011; (2) Spatial distribution information of open water bodies in Napahai Wetland extracted from 48 scenes of Landsat ETM images from 1990 to 2011.
The statistical data includes: (1) Open water area and optimal cumulative daily precipitation data of Napahai Wetland from May 1990 to August 2011; (2) Monthly average open water volume data of Napahai Wetland from 1988 to 2011; (3) Long-term monthly average open water volume and long-term monthly average precipitation data of Napahai Wetland.
This dataset is stored in .mdb, .gdb and .xlsx formats, with a compressed size of 792 KB.
The analytical research results of this dataset were published in *Journal of Natural Resources*, Volume 30, Issue 2, 2015.
