- Abstract:
- On the basis of coordinating utilization and protection of Bajiang River with the Shilin park，the remote image(2014) and land-use maps(1984, 1992) of the 1 000 meters wide riparian zones in the Bajiang banks in the Shilin County of Yunnan Province were analyzed using Geographic Information Technology for the adjustment of the riparian land use/land cover (LULC). The results showed that the obvious change of LULC happened over the last 30 years. The cropland area accounted for more than 56% of the whole studied area; the woodland area greatly reduced by 54%, grassland reduced by more than 95%. And on the other hand， the warehouse area increased by 106 times, the areas of the garden land and the rocky land increased by 7.6 and 1.7 times, respectively. The fragmentation happened in all kinds of the land-use types there. The directly driver of the changes is a development of the resident house, warehouse and public facilities land in the riparian zones. Although the role of Bajiang River was further recognized because of the Shilin park’s status of the World Heritage sites and UNESCO global geopark, the LULC improvement of the Bajiang riparian zones was not come into action. As the component of the Shilin world-level protected area and key landscape river in the Shilin County, the riparian LULC structure should be adjusted. The woodland area on the riparian banks should be increased by 77% compared to its percentage in 2014, which come from the 57% of the reduced rocky land area, 10% of the farming land area and 10% area of the housing land and warehouse area for afforestation. The adjustment should be preferentially carried out in the upper part of the Bajiang River Basin.
