Ecological Change Analysis of Lanzhou City Based on Remote Sensing Ecological Index

Ecological Status and Change by Remote Sensing

Evaluating ecological patterns and processes is crucial for the conservation of ecosystems [1]. In this view, remote sensing is a powerful tool for monitoring their status and change. This involves several tasks like biodiversity estimate, landscape ecology, and species distribution modeling, to name a few [2]. Due to the difficulties associated with field-based data collection [3], the use of ...

Advances of ecological remote sensing under global change

Call for Papers: In 21 st century, many factors conspire against the balance of ecosystems on earth, including climate change, population growth, and economic development. First, fast urbanization during the last few decades has altered the hydrologic cycle and related watershed processes that affect water resources and ecosystem dynamics in urban region. This urbanization combined with economi...

Bringing an ecological view of change to Landsat-based remote sensing

A satellite remote sensing based assessment of urban heat island in Lanzhou city , northwest China

As a promising application, quantitative remote sensing of urban heat island (UHI) could facilitate our understanding of urban/suburban environment and its relationship with urbanization. This paper investigates the urban heat island effect of Lanzhou, China, a densely built up city in a valley, based on Landsat ETM+ image acquired on April 22, 2000, whose spatial resolution is sufficient for m...

Spatial–Temporal Monitoring of Ecotonal Belt Using Landscape Ecological Indices in the Central Elburz Region: Remote Sensing and GIS Analysis

Iran has mountainous landscapes and half of its surface is occupied by highlands. Moreover, Iran is an arid country and deserts are located at lower altitudes. Most metropolitan areas are positioned in mid-altitudes between mountain and desert. Cities grow upwardly toward the highlands under pressures of urbanization and desertification. Foothill ecotones are a zone between upland mountains and...
