Prof., Dep. of Watershed Management Engineering, Faculty of Natural Resources, Sari Agricultural Sciences and Natural Resources University, Sari, Iran Journal Article 2023 09 02 Introduction: One of the most important steps towards sustainable development is the protection of land integrity, so that a part of the land is changed annually for several reasons, and the withdrawal of such lands from the production path creates irreparable damages. Given the high intensity of land use change in Mazandaran province, including the Haraz plain, which represents a significant environmental issues at both macro and spatial scales, the monitoring and analysis of theese changes can be considered a valuable tool for for the management and planning of land use. Considering that Haraz plain has not been spared from the crisis of destructive land use changes in recent decades, the need to monitor, highlight and process these changes as one of the most important management factors in this region is confirmed. Material and methods: In order to investigate land use changes, it is necessary to integrate a number of layers over a specific period of time. This research aims to investigate land use changes in Haraz Plain from 1980 to 2021. Therefore, Landsat data was employed to quantify the changes. By applying atmospheric, geometric, and radiometric corrections, image enhancement operations were performed and land use change maps were produced based on the supervised classification method, maximum likelihood algorithm and basis component analysis functions. The type of land use changes was determined from the difference function of the identification images and the accuracy of the maps using the overall accuracy test and the Kappa statistic. Results and discussion: The results showed that from 1980 to 1990, the area of forest lands decreased by 4 km2. The rangeland area also decreased from 450 to 436 km2. From 2000 to 2010, the area of forest land decreased from 272 to 270 km2 and rangeland decreased from 432 to 420 km2. Finally, between 2011 and 2021, the area of forest lands decreased by 9 km2 and the rangeland area decreased by 5 km2. The results indicated a reduction in the area of forest and rangeland, accompanied by an increase in the area of agricultural land and residential areas. Conclusion: The results obtained and the defined goals allow us to conclude that the area in question underwent changes in terms of its use during the considered statistical period (1980-2021). These changes were noticeable. Therefore, human factors interventions play a pivotal role in land use changes. The results of this study can assist planners in identifying the factors influencing land use changes and in making appropriate management decisions in the future.
