In this study are proposed impacts, management and functional planning criterion of forest road network system in rural and urban landscapes of Turkey. Road spacing and road density have been inspected concerning forest roads in production, reforestation, national parks and protection forests of rural and urban landscapes of Turkey. The forest road network was the most expensive human activity in the forests both in terms of economics and environmental effects. Public opinion about the environment has increased in recent years. Sustainable land use planning creates a great challenge for rural and urban road network planning. Further improvements of the network are necessary, to provide for people's needs in the near future. Harmful effects of road network conflict with the principles of sustainability. When making use of the forest ecosystem for various purposes, care must be taken not to spoil the forest structure. To achieve this, forests must be used according to forestry techniques. So, there is a need for a new planning approach, serving the interests of both accessibility and sustainable environment. In rural landscapes, forest road planning standards (slope, width, pavement, drainage etc.) are different in production, forestation, national parks and protection forests. The need for total forest roads in Turkey was 201,810 km, and that 133,693 km portion of which, corresponding to 66.25%, was constructed by the end of 2005. With a view to be capable of conducting modern forestry activities, our country's forests should be provided with a systematic road network by completing as soon as possible the construction of the remaining portion of such roads.
