New Utilization Model of Karst Rocky Desertified Land in Southwest China: Ecological Planting of Dendrobium officinale Kimura et Migo on Bare Rocky Mountains Mengyuan CHEN, Zisheng YANG* Institute of Land & Resources and Sustainable Development, Yunnan University of Finance and Economics, Kunming 650221, China Abstract The Yunnan-Guangxi-Guizhou rocky desertified area in southwestern China is one of the contiguous extremely poor areas identified in the Outline of Poverty Alleviation and Development in the Rural Areas of China (2011-2020). In rocky desertified areas, due to long-term severe soil erosion, large areas of bedrock are exposed or gravels are accumulated. This bare rock and gravel-mulched land has become the main land type in the rocky mountains. Under normal circumstances, it cannot be directly used for agriculture, forestry, animal husbandry, and fishery production, and is classified as land that is difficult to be utilized. In recent years, in Debao County, Baise City, Guangxi Zhuang Autonomous Region, as a deeply impoverished county in the Yunnan-Guangxi-Guizhou rocky desertified area, a new land use model of karst rocky desertified land, that is, planting Dendrobium officinale Kimura et Migo on bare rocky ground, has emerged, and certain poverty alleviation benefits have been achieved initially. In this article, on the basis of analyzing the suitability of planting D. officinale Kimura et Migo on karst rocky desertified land, the practice of planning D. officinale Kimura et Migo on the rocky desertified land in Debao County was elucidated, and then suggestions for reasonable promotion of ecological planting of D. officinale Kimura et Migo in karst rocky desertified areas were put forward.

Abstract: The Yunnan-Guangxi-Guizhou rocky desertified area in southwestern China is one of the contiguous extremely poor areas identified in the Outline of Poverty Alleviation and Development in the Rural Areas of China (2011-2020). In rocky desertified areas, due to long-term severe soil erosion, large areas of bedrock are exposed or gravels are accumulated. This bare rock and gravel-mulched land has become the main land type in the rocky mountains. Under normal circumstances, it cannot be directly used for agriculture, forestry, animal husbandry, and fishery production, and is classified as land that is difficult to be utilized. In recent years, in Debao County, Baise City, Guangxi Zhuang Autonomous Region, as a deeply impoverished county in the Yunnan-Guangxi-Guizhou rocky desertified area, a new land use model of karst rocky desertified land, that is, planting Dendrobium officinale Kimura et Migo on bare rocky ground, has emerged, and certain poverty alleviation benefits have been achieved initially. In this article, on the basis of analyzing the suitability of planting D. officinale Kimura et Migo on karst rocky desertified land, the practice of planning D. officinale Kimura et Migo on the rocky desertified land in Debao County was elucidated, and then suggestions for reasonable promotion of ecological planting of D. officinale Kimura et Migo in karst rocky desertified areas were put forward.
