The harmony between the natural and anthropogenic environments within the natural parks. Case study- The Viseu river basin

摘要

By definition a natural park is a protected area designed to protect and conserve the?natural environment in which the interaction between human activities and nature created a unique area, of significant environmental and cultural value and with great?biodiversity.The main purpose of these natural parks is to maintain the harmony between?humans and nature by protecting the biological diversity of the habitats and the?environment. In recent years both the natural and anthropic areas of the Vi?eu Basin have?been greatly damaged by extreme hydric phenomenon caused by the chaotic deforestation?of the area, increased precipitation, high pluvio-nival regime and the accentuated?asymmetry of the basin itself. By developing certain hydrographical installations and?conserving the protected areas a balance can be reached between the natural harmony and?the strict necessities of the anthropic habitats. The first priority of this developing is the environmental legislation and biodiversity protection.
