Naolihe National Nature Reserve is located in the hinterland of Heilongjiang Sanjiang Plain and is an important ecological function area in China. Based on remote sensing image data and hydrological data of the protected area, this paper inversed the vegetation coverage by pixel dichotomy, analyzed the spatial and temporal distribution characteristics of vegetation coverage in Naolihe Nature Reserve from 1984 to 2021, and studied the influence of precipitation and flooding frequency on vegetation coverage. Studies have shown that from 1984 to 2021, the low and middle vegetation coverage areas of Naolihe wetland first increased and then decreased, while the middle and high vegetation coverage areas showed the opposite trend. From the correlation coefficient between annual monthly precipitation and monthly vegetation coverage, the vegetation growth in Naolihe Nature Reserve is greatly affected by precipitation, which is positively correlated, and the response of vegetation coverage to precipitation is about one month behind. When the frequency of wetland flooding is between 0.45 and 0.50, the wetland vegetation grows well. The research can provide reference for Nalihe wetland ecological protection.

挠力河国家级自然保护区位于黑龙江三江平原腹地,是我国重要的生态功能区。基于遥感影像数据与保护区水文数据,通过像元二分法反演区域植被覆盖度,分析1984~2021年挠力河保护区植被覆盖度的时空分布特征,研究降水量与保护区淹水频率对于植被覆盖度的影响。结果表明,1984~2021年挠力河湿地低、中植被覆盖度地区呈先增后减趋势,中高植被覆盖度地区则反之。从保护区多年逐月降水与每年各月植被覆盖度的相关系数来看,挠力河保护区内植被生长情况整体受降水量影响较大,呈正相关,且植被覆盖度对降水量的响应为滞后约1个月。湿地淹水频率在0.45~0.50之间时,湿地植被长势良好。研究成果可为挠力河湿地生态保护提供参考。

挠力河国家级自然保护区位于黑龙江三江平原腹地,是我国重要的生态功能区。基于遥感影像数据与保护区水文数据,通过像元二分法反演区域植被覆盖度,分析1984~2021年挠力河保护区植被覆盖度的时空分布特征,研究降水量与保护区淹水频率对于植被覆盖度的影响。结果表明,1984~2021年挠力河湿地低、中植被覆盖度地区呈先增后减趋势,中高植被覆盖度地区则反之。从保护区多年逐月降水与每年各月植被覆盖度的相关系数来看,挠力河保护区内植被生长情况整体受降水量影响较大,呈正相关,且植被覆盖度对降水量的响应为滞后约1个月。湿地淹水频率在0.45~0.50之间时,湿地植被长势良好。研究成果可为挠力河湿地生态保护提供参考。

Naolihe National Nature Reserve is located in the hinterland of Heilongjiang Sanjiang Plain and is an important ecological function area in China. Based on remote sensing image data and hydrological data of the protected area, this paper inversed the vegetation coverage by pixel dichotomy, analyzed the spatial and temporal distribution characteristics of vegetation coverage in Naolihe Nature Reserve from 1984 to 2021, and studied the influence of precipitation and flooding frequency on vegetation coverage. Studies have shown that from 1984 to 2021, the low and middle vegetation coverage areas of Naolihe wetland first increased and then decreased, while the middle and high vegetation coverage areas showed the opposite trend. From the correlation coefficient between annual monthly precipitation and monthly vegetation coverage, the vegetation growth in Naolihe Nature Reserve is greatly affected by precipitation, which is positively correlated, and the response of vegetation coverage to precipitation is about one month behind. When the frequency of wetland flooding is between 0.45 and 0.50, the wetland vegetation grows well. The research can provide reference for Nalihe wetland ecological protection.
