دانلود کتاب Vegetation mapping

The volume on vegetation mapping treats one of the major objectives of vegetation science. In several other volumes in the handbook series some aspects of mapping were covered. This volume, however, has this topic as the prime objective. This made it necessary that auxiliar methods for selecting mapping units had to be covered in this volume, although these topics were extensively treated already in other volumes or are planned to be treated in coming volumes of the series. The volume was started by Dr. KUchler when Dr. TUxen was still editor of the series. The response to his first manuscript was so much delayed that the new developments in automated mapping methods, remote sensing and new goals for vegetation mapping made it necessary to write a complete new manuscript. I was very fortunate that Dr. KUchler was willing to write and edit a new manuscript, jointly with Dr. Zonneveld of ITC* in Enschede, after a new table of contents was generated. To get the cooperation of Dr. Zonneveld was another advantage for this volume. ITC in Enschede is one of the best vegetation mapping centers today, employing the latest developments in remote sensing, mapping routines, and field survey equipment. I thank both editors for their fine work. Though it was sometimes difficult for them to select individual topics for inclusion, the final decision was always made in the interest of the book as a whole. I hope, therefore, that the volume provides a general source book for everyone interested in vegetation mapping, for mapping at large and small scales for special topics in agriculture, forestry, or ecology. The respective volumes for the application of vegetation science in this handbook are greatly enhanced by the appearance of this volume on vegetation mapping. The two editors deserve thanks and respect for their work on behalf of our profession. I am sure the volume will be widely used in the future. Osnabriick, April 1988 H. LIETH
