紫色土区裸露地植被恢复技术

通过现场调查和样方调查法,分别调查衡阳市紫色岩裸露地的地形、地貌、气候、母岩、土壤等因子,以及植被分布、生态环境、植物生长等.在此基础上,采用对比研究法,有选择地进行植物及其配置模式的适宜性试验、整地方式的对比试验、宜林型紫色土经济林树种选择试验,评价不同立地条件类型下的植物适宜性与不同配置模式群落的生态适宜性及水土保持能力,最终筛选出不同立地条件类型下适宜的植物及其配置模式与整地方式,为紫色土裸露地植被恢复与宜林地经济开发提供理论依据和技术基础.表18,参11.

Restoration Technique of Vegetation in Bare Land of Purple Soil

The methods of field investigation and sampling survey were used to respectively investigate the topography,geomorphology,climate,parent rock,soil and other factors in Hengyang bare purple rock,as well as its vegetation distribution,ecological environment,the growth of plants and so on. On this basis,using comparative study method,selective suitability test for plants and their configuration mode,the contrast test of soil preparation and the selection test of tree species of economic forest in purple soil suitable for forests,were done to evaluate plant adaptability under different site conditions and ecological suitability and capability of soil and water conservation of different community configuration mode,which eventually screened out the plant and its appropriate configuration mode and soil preparation at different site conditions,to provide theoretical and technical basis for vegetation restoration in bare land of purple soil and economic development of land suitable for forests. 18tabs.,11refs.
