Abstract

Land environment changes can truly reflect the regional ecological environment and an important indicator for judging the regional ecological environment. Under the combined influence of natural factors and human activities, the land environment in Klang has undergone major changes. The analysis of land environment changes and their driving forces in the study area has a positive impact on optimizing the urban development space, enhancing the overall functions of the area and the carrying capacity of resources and the environment. This research takes Klang as the study area, because Klang is a coastal city and there are a lot of environmental dimensions to be observed. Studding from two dimensions of shoreline and land use, from the edge to the interior, to study the land environment of Klang as a whole. This research includes: shoreline change analysis, land use/cover change analysis, change driving force analysis, and policy recommendations are made based on the analysis results. Over the past 31 years, the total length of the shoreline has increased. The artificial shoreline has increased from 21.13km to 39.99km, and the proportion has increased from 13.52% to 24.71%. The proportion of biological shorelines dropped from 81.65% to 70.83%. The impact of human activities on the changes of shorelines is becoming more and more significant. Under the influence of development, the shoreline expands towards the sea as a whole. In terms of land use, agricultural land still dominates, but from 1990 to 2021, a large amount of agricultural land was converted into construction land. Although wetlands are declining, several wetland islands in the Klang area remain undeveloped in 31 years. Reserve land is sufficient, and the overall land environment is relatively stable.
