Tutor: Mr. Lau Hoi Lung (FYB 219); Phone 2609 6233; E-mail
Lecture Venue: ELB 403 (M1-3)
The course begins with an examination of the structure and functions of ecosystems and their impacts by humans, including erosion, bush fire, mining and deforestation. The landscapes to be examined include fung shui woods, agroecosystem, secondary woodlands, mangrove marsh, exotic plantations, fire-induced grasslands and urban forests. Land degradation and the restoration of degraded ecosystems will then be discussed, with special emphasis on the science, principles and practices of rehabilitation, as well as the management of woodland plantations for biodiversity preservation. Field trips are compulsory.
2. Ecosystem principles and concepts
3. Soils and ecosystem development
4. Fung shui woods in Hong Kong: biodiversity preservation and cultural legacy
5. Agroecology and agroecosystem
6. Mangrove ecology and management
7. Urban forestry: opportunities and constraints
8. Granitic landscapes in south China
9. Land degradation and restoration science: from theory to practice
10. Restoration of borrow area and quarries (soil destruction sites)
11. Fire ecology: soil, vegetation and ecosystem response
12. Restoration of fire-affected landscape (vegetation disturbance site)
13. Exotic woodland plantations and their transformation into native forests
14. Assessment of ecological restoration
Expected Learning Outcomes
The course focuses on interaction between people and ecosystems, natural or man-made. It complements the study of ecological impact assessment, which deals with ecological impacts, mitigation and auditing arising from project development. The importance of urban forests in sustaining a quality urban environment will also be addressed. After taking this course, students should be able to: (a) understand the principles and concepts of ecosystems, and their modification by humans; (b) understand the concepts of land degradation and practices of ecological restoration; (c) identify and understand the ecological and landscaping values, as well as the growth requirements of selected plant species in Hong Kong; (d) understand the values and practices of urban forestry in congested cities; and (e) develop appropriate working plans for the rehabilitation of degraded landscapes in Hong Kong and its neighboring region.
There will be lectures, field trips and quizzes for this course. Lecture powerpoints will be uploaded onto the WebCT so please read them before you come to the class. There are four field trips covering most of the issues addressed in the course, and there will be take-home quizzes on three of them. Field trip manuals will be uploaded on to WebCT in advance. Please observe all the instructions, including submission deadline of the quiz.
Each student is also required to submit a literature review of a specific topic by the end of February. The literature review requires you to conduct a vigorous search of library materials to enhance your reading, analytic and writing skills, and to clarify misconceptions. As the minimum length is 2,000 words, you need to select the most appropriate references and consolidate the ideas and concepts in a systematic manner. The topics of literature review will be announced after the add-drop period. A tutorial will be provided to help you with the writing of the literature review after the add-drop period. The learning activities, excluding your revision time, are summarized below.
All field trips are compulsory but students will only be quizzed afterwards on three of them. The quiz paper will be uploaded on to WebCT a week before the trip to facilitate early preparation. Please read the field trip manuals before the trip and record what you will see in the field. Each student has to contribute $20 (whole-day trip) and $15 (half-day trip) for the hire of coach while the department will absorb the balance.
