Abstract

The high density of buildings and roads are commonly associated with the Central Business District (CBD) of a metropolitan and multicultural city Karachi, Pakistan. It is the highly interactive place of a metropolis, therefore, considers functionally effective zones. This paper will prove even with a high rate of urbanization and expansion due to urban sprawl, still Saddar is the focus of attraction concerning several facts. The main objectives of the study were to explore the land-based cataloging of Saddar based on activity and to assess the environmental issues which are associated with this land use classification for the sustainability of CBD the people perception methods of identification of research, Land-use (LU) Analysis of Area of Interest (AOI) via, questionnaire-based surveying, and geo-coding of activities methods have been used in this study. The obtained results revealed that Saddar town covers land use approximately, 4.28% Leisure, 9.38% Shopping, Business or Trade, 7.9% Social, Institutional, or Infrastructure Related, 4.62% Mass Assembly of People, 6.37% Industrial, Manufacturing, and Waste Related, while 5.68% Traveler Movement,5.9% Natural Resource Related,52.40% Residential,3.4% No Human Activity or Unclassified. Approximately, 44.2% of the land use was engaged in capita producing activities, which reflects CBD’s functional strength. Overall, it recommended that there should be more green spaces in the CBD to improve air quality. Vertical urban gardening/forest can be implemented as Saddar has limited space and it is a concrete jungle having very less open space.

基于SRS/GIS技术的卡拉奇大都市中央商务区土地利用分析

建筑和道路的高密度通常与巴基斯坦卡拉奇大都市和多元文化城市的中央商务区（CBD）有关。它是一个大都市高度互动的地方，因此，考虑功能有效区。本文将证明，即使由于城市蔓延而导致的高城市化率和扩张，萨达尔仍然是几个事实的焦点。该研究的主要目的是探索基于活动的Saddar陆基编目，并评估与该土地利用分类相关的环境问题，以实现CBD的可持续性——人们对研究识别的感知方法，通过问卷调查对感兴趣区域（AOI）进行的土地利用（LU）分析，并且在本研究中使用了活动的地理编码方法。所获得的结果显示，萨德尔镇的土地利用率约为4.28%，购物、商业或贸易占9.38%，社会、机构或基础设施相关占7.9%，群众集会占4.62%，工业、制造业和废物相关占6.37%，而旅行者运动占5.68%，自然资源相关占5.9%，住宅占52.40%，无人类活动或未分类占3.4%。约44.2%的土地使用用于人均生产活动，这反映了CBD的功能优势。总的来说，它建议CBD应该有更多的绿地来改善空气质量。垂直城市园艺/森林可以实施，因为萨达尔的空间有限，而且是一个开放空间非常小的混凝土丛林。

期刊介绍： The fundamental task set by the editors of the journal is to bring together and present a diversity of research connected with ecology. Apart from the traditional ecological research areas, the scope of the journal will embrace more peripheral ecological issues connected with other disciplines of biology. Recognizing the increasing importance of the humanities in ecological research, the editors will strive to give such issues due representation in the journal. We hope to encourage the researchers contributing to the journal to adopt an unconventional approach to solving ecological problems, to go beyond classical, well-established conceptions, and to include methodological and anthropological issues. Such an approach is validated by the intensive development of the sciences bordering on both biology and the humanities that has been observed over recent years.
