Abstract

Ecological services are defined as the conditions and processes through which natural ecosystems and the species that comprise them, sustain and fulfill human life, or the goods and services provided by ecosystem which contribute to human welfare, both directly and indirectly. Ecological service value has been a hot topic in ecological economic research. Beijing, the capital of China, covers an area of more than 16,410 square kilometers and has a population of 14.93 million people. It's also a fast-growing city with rapid urbanization, which may significantly impact ecological services and functions. Such effects are difficult to quantify and are seldom taken into account in the policy making process. So this article tried a technical process for calculating the ecological service value based on remote sensing. Then the article estimated variations in ecological services value in response to land use changes in Beijing from 1990 to 2006, and provided useful information and advice to policy-making for sustainable development of ecological environment.
