摘要
为探究中国东北黑土区和美国密西西比河流域黑土区土地利用情况的差异,笔者通过Google Earth Engine平台解译得到两地2017年土地利用数据,对比两地土地利用结构和土地利用景观格局,并利用地理探测器对影响土地利用结构的自然因素进行分析。结果表明:中国黑土区和美国黑土区土地利用结构相似,土地利用结构指数分别为-11.30、-56.11,中国黑土区土地利用格局相对较好;气候对两地土地利用结构影响最大(99.90%),其次为地质条件(93.00%),自然因素综合作用的影响相对较大;中国黑土区可借鉴美国保护性耕作方式,提高土地利用潜力,在提高粮食生产能力的同时稳定其生态功能。
In order to explore the differences in land use between the black soil areas in Northeast China and the Mississippi River basin in the United States,the authors compared the land use structure and landscape pattern of the two areas based on the land use data obtained by Google Earth Engine in 2017.The natural factors affecting land use structure were also analyzed by geographic detector.The results show that:the land use structure of Chinese black soil area is similar to that of the United States,and the land use structural index of the two areas were-11.30 and-56.11,which showed the land use pattern of Chinese black soil land is relatively better.It was found that climate had a greater influence(99.90%),followed by geological conditions(93.00%),and the comprehensive influence of natural factors had a greater effect.The black soil areas in China should learn the methods from the United States conservation tillage to improve the land use potential and stabilize the ecological function while improving the grain production capacity.
