The impact of human factors on the change in vegetation cover of the be river basin in the period from 2000 to 2015

The Be river basin is located in the area with a rapid urbanization rate and a large immigrants proportion annually. Therefore, the population growth rate for the period from 2000 to 2015 in the river basin is up 3,53% which is 3,27 times as high as the population growth rate of Vietnam. These are the major causes leading to the fluctuation in vegetation cover of the Be river basin during over time. | TRƯỜNG ĐẠI HỌC SƯ PHẠM TP HỒ CHÍ MINH HO CHI MINH CITY UNIVERSITY OF EDUCATION TẠP CHÍ KHOA HỌC JOURNAL OF SCIENCE KHOA HỌC TỰ NHIÊN VÀ CÔNG NGHỆ NATURAL SCIENCES AND TECHNOLOGY ISSN: 1859-3100 Tập 15, Số 9 (2018): 53-62 Vol. 15, No. 9 (2018): 53-62 Email: tapchikhoahoc@; Website: THE IMPACT OF HUMAN FACTORS ON THE CHANGE IN VEGETATION COVER OF THE BE RIVER BASIN IN THE PERIOD FROM 2000 TO 2015 Phan Van Trung1*, Nguyen Tham2 1 2 Thu Dau Mot University University of Education – Hue University Received: 17/7/2018; Revised: 21/8/2018; Accepted: 21/9/2018 ABSTRACT The Be river basin is located in the area with a rapid urbanization rate and a large immigrants proportion annually. Therefore, the population growth rate for the period from 2000 to 2015 in the river basin is up 3,53% which is 3,27 times as high as the population growth rate of Vietnam. These are the major causes leading to the fluctuation in vegetation cover of the Be river basin during over time. This research used methodologies including data collection, statistical analysis, mapping method and geographic information system to evaluate the impact of human factors to the vegetation cover fluctuation of the Be river basin in the period from 2000 to 2015. Based on the results of change map in the vegetation cover, a research group set up fluctuating matrix, analyze to clarify the vegetation coverfluctuation situation due to human’s impacts in the Be river basin in the period from 2000 to 2015. Keywords: the change, vegetation cover, the Be river basin, human factor. TÓM TẮT Tác động của nhân tố nhân sinh đến biến động lớp phủ bề mặt lưu vực sông Bé giai đoạn 2000 – 2015 Lưu vực sông Bé nằm trong vùng có tốc độ đô thị hóa nhanh, lượng dân nhập cư hàng năm lớn, do đó tỉ lệ tăng dân số ở lưu vực giai đoạn 2000 – 2015 lên đến 3,53% gấp 3,27 lần so với cả nước. Đây là những nguyên nhân chính dẫn đến biến động lớp phủ bề mặt lưu vực sông Bé trong thời gian vừa qua. .
