| 中文摘要:Land use classification plays an important role in adjusting land structure and developing land resources reasonably, especially in the farming area. The objective of this research is to choose an appropriate method to classify land use type in the farming area. A new classification method, random forest (RF) classifier, was applied to make land use mapping in agricultural cultivation region with multi source information, including multi seasonal spectrum, texture and topographic information. The best classification scheme was chosen to extract land use information, and RF algorithm was used to reduce the dimension of characteristics variables. The RF algorithm, support vector machine, and maximum likelihood classification were used to map agricultural land use, and the applicability of these three different classification methods was analyzed. The result shows that RF classification of land use classification with multi source information effects best, the overall accuracy and Kappa coefficient are 85.54% and 0.8359 respectively. Feature selection method from RF algorithm can effectively reduce the data dimension and ensure the accuracy of classification at the same time. Compared with these three classification methods, RF algorithm performs the highest overall accuracy of 81.08%, which is respectively 9.46% and 5.27% higher than support vector machine and maximum likelihood classification. It is an effective scheme that makes land use classification in the farming area using RF classifier with multi-source information. It provides a fast and feasible method for the division of land use types. |

| Abstract: |
Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
