The present study focuses on the patterns of urbanization process in Netherlands as a whole and within the “Green Heart” in particular. The present study finds over the last decades, the Green Heart is under attack from suburbanization of larger and smaller settlements as several political concessions have been made to local development needs. The Green Heart is also affected by the construction of new roads and railway lines. This infrastructure is built for tangential transport of an increasing volume of commuters. The spatial policies for preserving green spaces suffer from a dilemma between two contradicting functions of green space in a regional context: to be a separator of urban and rural areas and to be an integrator towards the Regional City of “Green Metropolis”.展开更多
