Existing urban expansion simulation models focus on the mining of spatial neighborhood features among driving factors, however, they ignore the over-fitting, gradient explosion, and vanishing problems caused by the long-term dependence of time series data, which results in limited model accuracy. In this study, we proposed a new dynamic urban expansion simulation model. Considering the long-time dependence issue, long short term memory (LSTM) was employed to automatically extract the transformation rules through memory units and provide the optimal attribute features for cellular automata (CA). This study selected Lanzhou, which is a semi-arid region in Northwest China, as an example to confirm the validity of the model performance using data from 2000 to 2020. The results revealed that the overall accuracy of the model was 91.01%, which was higher than that of the traditional artificial neural network (ANN)-CA and recurrent neural network (RNN)-CA models. The LSTM-CA framework resolved existing problems with the traditional algorithm, while it significantly reduced complexity and improved simulation accuracy. In addition, we predicted urban expansion to 2030 based on natural expansion (NE) and ecological constraint (EC) scenarios, and found that EC was an effective control strategy. This study provides a certain theoretical basis and reference value toward the realization of new urbanization and ecologically sound civil construction, in the context of territorial spatial planning and healthy\/sustainable urban development.<\/jats:p>","DOI":"10.3390\/rs13081499","type":"journal-article","created":{"date-parts":[[2021,4,13]],"date-time":"2021-04-13T22:55:09Z","timestamp":1618354509000},"page":"1499","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":45,"title":["Simulation of Dynamic Urban Expansion under Ecological Constraints Using a Long Short Term Memory Network Model and Cellular Automata"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7232-7403","authenticated-orcid":false,"given":"Jiamin","family":"Liu","sequence":"first","affiliation":[{"name":"College of Earth and Environment Sciences, Lanzhou University, Lanzhou 730000, China"},{"name":"The Key Laboratory of Western China\u2019s Environmental Systems, Ministry of Education (MOE), Lanzhou 730000, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2108-152X","authenticated-orcid":false,"given":"Bin","family":"Xiao","sequence":"additional","affiliation":[{"name":"College of Earth and Environment Sciences, Lanzhou University, Lanzhou 730000, China"},{"name":"The Key Laboratory of Western China\u2019s Environmental Systems, Ministry of Education (MOE), Lanzhou 730000, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9448-9879","authenticated-orcid":false,"given":"Yueshi","family":"Li","sequence":"additional","affiliation":[{"name":"College of Earth and Environment Sciences, Lanzhou University, Lanzhou 730000, China"},{"name":"The Key Laboratory of Western China\u2019s Environmental Systems, Ministry of Education (MOE), Lanzhou 730000, China"}]},{"given":"Xiaoyun","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Earth and Environment Sciences, Lanzhou University, Lanzhou 730000, China"},{"name":"The Key Laboratory of Western China\u2019s Environmental Systems, Ministry of Education (MOE), Lanzhou 730000, China"}]},{"given":"Qiang","family":"Bie","sequence":"additional","affiliation":[{"name":"College of Earth and Environment Sciences, Lanzhou University, Lanzhou 730000, China"},{"name":"The Key Laboratory of Western China\u2019s Environmental Systems, Ministry of Education (MOE), Lanzhou 730000, China"},{"name":"Faculty of Geomatics, Lanzhou Jiaotong University, Lanzhou 730070, China"}]},{"given":"Jizong","family":"Jiao","sequence":"additional","affiliation":[{"name":"College of Earth and Environment Sciences, Lanzhou University, Lanzhou 730000, China"},{"name":"The Key Laboratory of Western China\u2019s Environmental Systems, Ministry of Education (MOE), Lanzhou 730000, China"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Li, S., Bing, Z., and Jin, G.
