- 摘要:
- 黑龙江省三江平原位于黑龙江省东北部,土地总面积10万km2,是国家重要的商品粮基地。在我国粮食安全体系建设中,黑龙江省三江平原占有重要地位。及时掌握黑龙江省三江平原地区土地利用状况及其15年来的变化趋势,对优化区域土地利用结构和土地资源的可持续利用,全面贯彻统筹区域经济和社会协调发展的战略部署,促进东北区域经济协调发展具有十分重要的意义。以TM遥感影像为信息源,运用遥感及地理信息系统技术、数理统计等方法,对黑龙江省三江平原土地利用变化的特征、空间动态变化进行了分析,结果表明:在过去的15a里,三江平原耕地面积发生了重大变化,土地利用类型间转换显著,未利用土地向耕地转换是黑龙江省三江平原土地利用转换的一个主要类型。
- Abstract:
- Sanjiang Plain is located in the northeast of Heilongjiang province,and its total land area is 1000 000 km2,it is the important commodity grain base of the country.Sanjiang Plain has occupied the important position in the construction of China’s food security system.Timely grasp the land use status in the Sanjiang Plain and the trend of changes in the Sanjiang Plain during fifteen years,this has very important significance on the structure of optimizing regional land use and the sustainable utilization of land resource,general implemention of the overall development of regional economy and the strategic deployment of coordinating social development,promoting the coordinated development of northeastern regional economy.This paper selected TM image,and be used as information source,applying remote sensing and the technology of GIS and application of mathematical statistics methods,and analyzing the character of the change of land use and space-time dynamic change in the Sanjiang Plain.The results showed that cultivated area of Sanjiang plain had great changes,land use types conversion was significant,unutilized land was to convert cultivated land,which was a major type of land use conversion in the Sanjiang Plain of Heilongjiang province.
