Urban land use suitability evaluation is the basic work of urban land use planning and management. The evaluation method is a core in urban land use suitability evaluation. Traditional urban land use suitability evaluation methods are GIS-based methods which often can not get satisfactory results for the complex nonlinear urban land use system. Artificial neural network is a frontier theory of complex non-linearity scientific and artificial intelligence science. It is a new method to evaluate urban land use suitability. This paper took the land use suitability evaluation of Hefei city as an example, building a back propagation neural network with 8 neurous of input layer, 5 neurons of hide layer and 3 neurons of output layer. The analysis shows: the high suitability area is 682.27 km2in Hefei city, being about 8.73% of the total study area; the middle suitability area is 5965.76 km2, or about 76.33% of the total area and the low suitability area is 1167.35 km2, or about 14.94% of the total area. The results reflect the actual situation in Hefei city. The study shows that the back propagation neural network model can overcome the shortcomings of traditional evaluation methods. It means that artificial neural network is suitable for urban land use suitability evaluation. This reflects that artificial neural network has great academic value and application prospect in urban land use suitability evaluation. It also reflects that this study can provide a new idea and method for urban land use suitability evaluation.

Land use and land cover change (LUCC) is an important issue in global environmental change and sustainable development, yet spatial simulation of LUCC remains challenging due to the land use system complexity. The cellular automata (CA) model plays a crucial role in simulating LUCC processes due to its powerful spatial computing power; however, the majority of current LUCC CA models are binary-state models that cannot provide more general information about the overall spatial pattern of LUCC. Moreover, the current LUCC CA models rarely consider background artificial irrigation in arid regions. Here, a multiple logistic-regression-based Markov cellular automata (MLRMCA) model and a multiple artificial-neural-network-based Markov cellular automata (MANNMCA) model were developed and applied to simulate complex land use evolutionary processes in an arid region oasis (Zhangye Oasis), constrained by water resources and environmental policy change, during the period 2000–2011. Results indicated that the MANNMCA model was superior to the MLRMCA model in simulated accuracy. Furthermore, combining the artificial neural network with CA more effectively captured the complex relationships between LUCC and a set of spatial driving variables. Although the MLRMCA model also showed some advantages, the MANNMCA model was more appropriate for simulating complex land use dynamics. The two integrated models were reliable, and could reflect the spatial evolution of regional LUCC. These models also have potential implications for land use planning and sustainable development in arid regions.

Penelitian ini bertujuan untuk mengkomparasikan akurasi metode ANN dan LR dalam memprediksi perubahan lahan sawah di Kabupaten Purworejo. Adapun data masukan yang dibutuhkan adalah peta lahan sawah tahun 2008, 2015 dan 2019 hasil interpretasi visual citra satelit resolusi tinggi dan faktor pendorong perubahan lahan sawah. Hasil penelitian menunjukkan bahwa model prediksi lahan sawah yang dibangun dari ANN dan LR secara umum memiliki akurasi yang sama-sama baik. Tetapi jika dilihat dari total nilai false alarm dan misses, model CA yang dibangun dari ANN lebih baik dari LR. Hasil penelitian ini juga menunjukkan bahwa dalam rentang tahun 2008 sampai 2019, luasan lahan sawah di Kabupaten Purworejo berkurang sekitar 194.01 Ha.  Kata kunci: artificial neural network; cellular automata; logistic regression; perubahan penggunaan lahan; sawah.  This research aims to compare the accuracy of the ANN and LR methods in predicting changes in paddy fields in Purworejo Regency. The input data required is a map of paddy fields in 2008, 2015 and 2019 as a result of visual interpretation of high-resolution satellite imagery and the driving factors for changes in paddy fields. The results showed that the paddy field prediction model built from ANN and LR generally has the same accuracy. But if it is seen from the total value of false alarms and misses, the CA model from ANN is better than LR. This study shows that from 2008 to 2019, the area of paddy fields in Purworejo Regency decreased around 194.01 Ha. Keywords: artificial neural network; cellular automata; land-use changes; logistic regression; paddy field.
