ASSESSMENT OF THE MAIN COMPONENTS OF THE NATURAL AND RECREATIONAL POTENTIAL OF THE TENIZ-KORGALZHYN DEPRESSION USING GEOINFORMATION TECHNOLOGIES AND REMOTE SENSING METHODS

Abstract

This article presents the research results and the development of a methodology for assessing the components of the natural and recreational potential of the Teniz-Korgalzhyn depression focusing on its suitability for recreation and ecotourism development. The aim of the study is to analyze the key components of the natural environment that form the basis of the recreational potential of the Teniz-Korgalzhyn depression, utilizing geoinformation technologies and remote sensing techniques. The proposed method allows for a detailed component-by-component analysis of the region's natural and recreational resources, including relief, water resources, and vegetation. The balance method was used to calculate the potential, providing an objective assessment and comparative analysis of the territory's potential. The methodology presented in the article not only determines the priority areas of recreational activity but also allows for assessing degree of accessibility of the natural and recreational resources of the area under study. As a result of the assessment of the region's resources, territories more favorable for the development of ecotourism were identified. Analysis of landscape data obtained using NDVI and MNDWI revealed differences in the natural and recreational potential of the Teniz-Korgalzhyn Depression areas. Areas with a high NDVI value are characterized by an abundance of vegetation, which indicates their potential suitability for recreational use. On the contrary, areas with low NDVI and high MNDWI indicate insufficient vegetation, but the possible presence of water bodies, which is also important for recreational planning. These differences demonstrate a clear comparative analysis of data on the two indices and allow for reasonable distribution of recreational resources, assessment of ecosystem degradation, and identification of priority areas for restoration and protection. Key findings highlight the region's diverse natural resources, influenced by climatic variability, anthropogenic factors, and habitat diversity. Water resources, essential in the continental climate, are vital for recreation but necessitate sustainable management to avoid ecosystem degradation. The findings underline the importance of sustainable resource use to preserve the ecological balance and promote tourism in the region. The Korgalzhyn Nature Reserve emerges as the most valuable natural asset, although much of the steppe ecosystem remains unprotected and requires ecological monitoring.
