China is one of the developing countries with vast desertification affected areas and a certain percentage of her population is living in the affected areas. As a large country with dense population and complex environmental conditions, China is fully aware that the desertification combating is of importance to the global sustainable development of environment and economy. Desertification affected areas in China are mainly distributed in arid, semi- arid and dry sub-humid areas in China, covering 471 countries in 18 provinces and autonomous regions in the west part of the Northeast, the northern part of the North China and the most regions of the Northwest China. The area affected by Desertification in China is approximately 2.622 million ㎢. It covers 27.3% of the total territory of China. It is estimated that the annual spreading ratio of desertification in China is 2,460 ㎢. After Republic of Korea and P. R. China setup diplomatic relation in 1993 and based on the agreement between two countries, and in the 4th Sino-Korea Science & Tech. Cooperation Commission held in Seoul, Korea in Dec. 12, 1996. The joint research project titled Desertification combating and Sand Industry Development has been approved between Beijing Forestry University and Seoul National University. The duration of cooperation for first stage is from 1997 to 2000, and the main contents of the Joint Research Project are the studies of silviculture technology for landscape-eco-shelterbelt system construction, introduce and test of fine plant species for combating desertification, the uses of new materials & high tech. In desertified-land development, and sand industry development in desertification area.

The purpose of this study was to figure out the suitable field standards for revegetation measures on cut-slopes in consideration of the environmental factors. The field survey was conducted from 1995 to 1996 on highway cut-slopes. The results obtained could be summarized as follows; The major revegetation measures surveyed were 5 major measures as a whole in descending order of seed-spraying measures, block-sod pitching measures, latticed block pitching measures, hydro-seeding measures with seed-fertilizer-soil materials, and several netting measures on highway cut-slopes. According to the analysis of the environmental factors, the plant coverage was affected several major environmental factors which were soil factors(soil hardness, soil texture, soil and rock condition), and site factors(slope gradient, slope length). From a viewpoint of optimum selection, the major 3 factors(soil factors, slope gradient factors, slope length factors) should be considered for selection of revegetation measures on highway cut-slopes.

The second year`s results of surface fire effects on forest vegetation and soil properties and fire tolerance of various tree species were investigated in Mt. Gwanak, Kyunggi-do, successively after the study of the first year`s effect in the same place. Soil moisture contents, organic matters, and most of soil nutrients including exchangeable bases had increased just after fire and went down to become somewhat constant. Available phosphorous at fired area decreased until it became similar to that at unfired area, while pH of subsoil was continuously increasing from just after fire till after 1 year. For Lespedeza and Weigela species, fire tolerance of tree crown was the lowest but reproductive capacity was the highest, And both of them were high for Rhododendron species. More exact classification into Increasers, Decreasers, Invaders and Neutral species was possible in the second year`s study. According to comparison of similarities, it was found that the vegetational structure at fired area is slowly restoring to original state as time goes.

수도권 지역내 암반황발산지의 안정녹화공법 개발에 관한 연구

우보명 한국조경학회 1987 韓國造景學會誌 Vol.15 No.1

In Seoul metropolitan area, rockily denuded fores lands are widely distributed. Out of the rock-exposed hillslopes, Kwanak-Samsung mountains and Bookhan-Dobong mountains areas are the most severely eroded land at present To develope the rehabilitation measures for the rock-exposed hillslopes, it is essentially required that mechanisms of rock debris production and movement from the rock-exposed hillslopes should be studied. And also, suitable experiments for planting techniques should be practised at the field level. In this context, some experiments for the on-site fixation of the unstable stone-debris including plantation establishments on the rock-exposed hillslopes, have been carried out for 4 years from 1983 to 1986 at Kwanak mountain hillslopes. The results may be summarized as follows : 1) The soil environment-tolerable tree species for plantation extablishment on rock-exposed hillslopes include Buxus microphylla var. koreana, Forsythia koreana, Juniperus chinensis var. sargentii, Alnus hirsuta and Pinus rigida. These trees have, however, been showed fairly good growth performence at the places having more than about 30cm of soul layer depth above rock-bed. 2) In raising of seedlings to plant on the rock-exposed hillslopes, containerized seedling practices knave been appeared as the most adoptable measures. 3) In fixation of the unstable stole debris-and-sands on the on-site of rock. exposed hillslopes, the stone-lined barrier measures are more effective at comparatively large-sized places of rock-exposed hillslopes while the stone-bowed barrier measures are more effective at small-sifted isolated sold-debris places. The stone-buttressed terraces measures are more effective at the soil-composed hillslopes rather than rock-exposed hillslopes.

This study was carried out from June 1996 to November 1997 to analyze the growth characteristics of the introduced species revegetated on highway cut-slopes. The number of revegetation measures type surveyed were fourteen such as seed-spraying measures, block-sod pitching measures, and hydro-seeding measures with seed-fertilizer-soil materials. The introduced species for revegetation measures were mostly Festuca arundinancea(cool season grass), Eragrostic curvula(warm season grass), Lolium perenne(cool season grass), Dactylis glomerata(cool season grass), Poa pratensia(cool season grass). The species diversity index of the upper part on highway cut-slopes were greater than that of the middle part and lower part. The growth of introduced species was good on north-facing cut-slope than the others and that was flourish in temperate north forest zone. Also, the introduced species seemed to decrease or disappear, while the ratio of native woody and herb species which were in mature stage seemed to increase.
