This study develops a new method for identifying irrigation in northeastern China by comparing canopy moisture between the cropland and adjacent natural ecosystems (i.e., forests). This method is based on two basic assumptions, which we validated using field survey data. First, the canopy moisture of irrigated cropland, indicated by a satellite-based land surface water index (LSWI), is higher than that of the adjacent forest. Second, the difference in LSWI between irrigation cropland and forest is larger in arid regions than in humid regions. Based on the field survey and statistical dataset, our method performed well in indicating spatial variations of irrigated areas. Results from this study suggest that our method is a promising tool for mapping irrigated areas, as it is a general and repeatable method that does not rely on training samples and can be applied to other regions.<\/jats:p>","DOI":"10.3390\/rs11070825","type":"journal-article","created":{"date-parts":[[2019,4,5]],"date-time":"2019-04-05T11:36:01Z","timestamp":1554464161000},"page":"825","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Mapping Irrigated Areas of Northeast China in Comparison to Natural Vegetation"],"prefix":"10.3390","volume":"11","author":[{"given":"Kunlun","family":"Xiang","sequence":"first","affiliation":[{"name":"Guangdong Province Key Laboratory for Climate Change and Natural disaster Studies, Zhuhai Key Laboratory of Dynamics Urban Climate and Ecology, School of Atmospheric Sciences, Sun Yat-sen University, Guangdong, Zhuhai 519082, China"}]},{"given":"Minna","family":"Ma","sequence":"additional","affiliation":[{"name":"Guangdong Province Key Laboratory for Climate Change and Natural disaster Studies, Zhuhai Key Laboratory of Dynamics Urban Climate and Ecology, School of Atmospheric Sciences, Sun Yat-sen University, Guangdong, Zhuhai 519082, China"}]},{"given":"Wei","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Vegetation and Environmental Change, Institute of Botany, the Chinese Academy of Sciences, Beijing 100093, China"}]},{"given":"Jie","family":"Dong","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Earth Surface Processes and Resource Ecology, Beijing Normal University, Beijing 100038, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6660-2034","authenticated-orcid":false,"given":"Xiufang","family":"Zhu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Earth Processes and Resource Ecology, College of Resources Science and Technology, Beijing Normal University, Beijing 100875, China"}]},{"given":"Wenping","family":"Yuan","sequence":"additional","affiliation":[{"name":"Guangdong Province Key Laboratory for Climate Change and Natural disaster Studies, Zhuhai Key Laboratory of Dynamics Urban Climate and Ecology, School of Atmospheric Sciences, Sun Yat-sen University, Guangdong, Zhuhai 519082, China"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,5]]},"reference":[{"key":"ref_1","unstructured":"Bruinsma, J.
