Land Use Pattern Adjustment under Ecological Security: Look for Secure Land Use Pattern in China

Abstract

Since China adopted reform and open policy in 1978, intensive land use pattern changes have taken place at different scales with the rapid economic growth and fast urbanization, resulting in complex impacts on the regional eco-environmental security. Based on some case studies in Shenzhen, Beijing and the grassland and farming-pastoral zone of North China, three models, namely City Expansion Model in Metropolitan Area in Beijing, Basin Rainfall-runoff Model in Shenzhen, and Land Use Pattern Adjustment Model in the grassland and farming-pastoral zone of North China were used to try to demonstrate the possibility of promoting ecological security level in China by implementing the rational land use pattern adjustment.
