摘要

在果阿,旅游业是经济的主要基石。随着沿海地区游客数量的增加,海岸管制区内出现了更多与旅游业相关的基础设施。敏感和脆弱的沿海地区被混凝土结构覆盖,沿海环境变得容易退化。本文的目的是利用遥感数据和地理空间技术研究Salcete taluka海岸管制区土地利用和土地覆盖的变化。为了实现这一目标,同时使用了主要和次要数据。主要数据基于个人观测和实地考察,次要数据包括地形图、LANDSAT 7 ETM和LANDSAT 8卫星图像,这些图像使用ArcGIS 10.3、ERDAS IMAGINE 2014、SAGA(自动地球科学分析系统)和MS Excel进行处理和分析。从17年(2000-2017)的土地利用和土地覆盖分析中发现,随着旅游活动和相关基础设施的增加,CRZ内的土地覆盖发生了巨大变化。分析显示,农业面积减少,而建成区、荒地和植被面积增加。使用SAGA软件的变化检测分析可以理解不同类别之间的转换。研究表明,Salcete海岸沿线越来越多的游客和旅游活动正在恶化环境,扰乱固有的海岸景观。

Human-Induced Landscape Alteration in the Coastal Regulation Zone of Goa, India, from 2000 to 2017
In Goa, the tourism industry is the major cornerstone of the economy. With the increasing number of tourists along the coastal areas, more tourism-related infrastructure is emerging within the Coastal Regulation Zone. The sensitive and fragile coastal zones are being covered by concrete structures and the coastal environment becomes vulnerable to degradation. The objective of the paper was to study the changes in landuse and landcover in the Coastal Regulation Zone of Salcete taluka using remote sensing data and geospatial techniques. To fulfill the objective, both primary and secondary data were used. Primary data was based on personal observations and field visits while secondary data consisted of topographic maps, LANDSAT 7 ETM, and LANDSAT 8 satellite images, which were processed and analyzed using ArcGIS 10.3, ERDAS IMAGINE 2014, SAGA (System for Automated Geoscientific Analyses) and MS Excel. From the landuse and landcover analysis for a period of 17 years (2000-2017), it was found that the land cover within the CRZ underwent a tremendous change with the increase in tourism activity and related infrastructure. The analysis revealed that the agricultural area has decreased, whereas built-up areas, barren land, and vegetation area increased. The change detection analysis using SAGA software allowed to understand the conversion between different classes. The study revealed that the increasing number of tourists and tourism activities along the Salcete Coast is deteriorating the environmental setup and disturbing the inherent coastal landscape.

期刊介绍: Journal “GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY” is founded by the Faculty of Geography of Lomonosov Moscow State University, The Russian Geographical Society and by the Institute of Geography of RAS. It is the official journal of Russian Geographical Society, and a fully open access journal. Journal “GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY” publishes original, innovative, interdisciplinary and timely research letter articles and concise reviews on studies of the Earth and its environment scientific field. This goal covers a broad spectrum of scientific research areas (physical-, social-, economic-, cultural geography, environmental sciences and sustainable development) and also considers contemporary and widely used research methods, such as geoinformatics, cartography, remote sensing (including from space), geophysics, geochemistry, etc. “GEOGRAPHY, ENVIRONMENT, SUSTAINABILITY” is the only original English-language journal in the field of geography and environmental sciences published in Russia. It is supposed to be an outlet from the Russian-speaking countries to Europe and an inlet from Europe to the Russian-speaking countries regarding environmental and Earth sciences, geography and sustainability. The main sections of the journal are the theory of geography and ecology, the theory of sustainable development, use of natural resources, natural resources assessment, global and regional changes of environment and climate, social-economical geography, ecological regional planning, sustainable regional development, applied aspects of geography and ecology, geoinformatics and ecological cartography, ecological problems of oil and gas sector, nature conservations, health and environment, and education for sustainable development. Articles are freely available to both subscribers and the wider public with permitted reuse.
