TRANSFORMATION AND UTILISATION OF HOLOCENE BARS ALONG THE COAST OF SOUTH CHINA
1990, 45 (4):
The sand bars along the coast of South China were formed in middle and late Holocene according to 105 dating data. They may be grouped into 6 periods. Having analysed the grain size and sediriientary characteristics of the bars in each period, and the regular distribu-tion of littoral bar, baymouth bar, totnbolo and offshore barrierbar, the author, holds the view that the formation of Holocene bars along the coast of South China is closely related to abun-dant source of sand, powerful wave, sea-level close to the present, stable neotectonic movement and the monsoon. The major harmful effects of the bars are: 1. damage caused by wind-drift sand, 2. the baymouth bars woud block the channels. This paper offers a proposal of inter-planting sand-fixing trees consisting of conifer and deciduous with herbaceous and shrub. The major favourable factors are: 1. the abundant placer resources, 2, the multitudinous bar-lagoon bars, 3, a wide space for the development of agriculture, forestry, stock raising and fish-culture, 4. a valuable, land for the exploitation of special economic zone, economic develop-ment district and seaside 'tourism.
