水产养殖遥感监测及信息自动提取方法研究

REMOTE SENSING MONITORING OF AQUACULTURE AND AUTOMATIC INFORMATION EXTRACTION

以海南省文昌地区为例,在沿海地区尝试利用遥感监测的手段提取水产养殖地块和面积。采用面向对象的分类方法进行监测,取得了理想效果,同时也提出了提高分类精度的建议。

Aquaculture constitutes one of the important agricultural production means in China and has a significant irreplaceable effect on the development of economy.The monitoring and scientific management of aquaculture is therefore especially important to the people.At present,researches on the remote sensing monitoring of aquaculture are very insufficient both at home and abroad.With Wenchang area of Hainan Province as an example,the authors tentatively extracted the aquaculture area by means of remote sensing.The object-oriented classification method was adopted in the monitoring and,as a result,an ideal result was obtained.Some suggestions are put forward for further improving the classification precision.
