Under the human being’s intervention, for the specific goal, vegetation’s increase which can be realiszed under the theory instruction and technique , all may be called greening. But using plant to make scenery in park in a certain mean is not belong to greening. Most important content of greening include afforestation, breeding nursery, protecing forest, and many other increase in vegetation is also belong to greening.Greening produces under the certain historical condition.. Regional greening is an important way to solve contradiction between people and land. At different period, the acquit of contradiction between people and land is different, the quality and the quantity request of regional greening is dissimilar. The Nature, Status and Function of regional greening are always relate with the specific social development stage. At different period, the leading greening role of our society , decides the feature and social characteristics of regional greening.Regional greening comport strong characteristic of primary stage. First, basing on the division of historical periods, we conlude that the development of regional greening undergoes three stages:ancient, esent , modern and the radical change of regional greening. The decade of ancient stage is before The Opium War. It can be divided into four stages baseing on the condition of productivity, the degree of greening and environment background, that is the seeds of greening, the formation of greening system, the greatest prosperity period in the development of greening and the last development stage. The modern regional greening period is from the founding of People’s Republic of China to 1997. According to policy tremendous change and the adjustment of goal, this stage is devided into technique rising of greening, tortuous development of regional greening, vigorous development of regional greening. From 1998, the conception of regional greening and historic Conversions of the Policies of forestry has the essential difference with the former one, so it is an independent stage.China’s regional greening, originally produces from the agricultural production. It is because of the low productive of the anciental time, at that time, the purpose of humanity produce was content their food and clothing, after further development in productivity, it became the supplement of agriculture. Take beautifies, protection, commemoration and so on as the goal was also one aspect of regional greening, but its extension and scope standard is limited. In Ming dynasty, the purpose of commodity appear. Parts of regional greening developed towards the industrialization development. From Qing dynasty to the early period of the republic of China, along with the input of other countries’ ideology of forestry construction and scientifictechnology, with ecological environment problem, the goal of regional greening became changing environment. Affected by the present occasion country condition, the goal of regional greening was support woods and accessory product of forest.Until the end of the country, the goal of greening was changing environment and developing economy, and considering other requirements.After the Changjiang Flood, our leader began think about the direction of forestry development in the future, our goal became using natural forest protecting and returning land for faming to forestry, pursuteing ecological benefit.To realize the present goal of greening, we should make patition of greening, that is to divided it according to it’s similarity and difference, to get the assemblage of similar condition and natural condition. The former natural zoning is greening zoning’s reference and foundation, and it should carry through a certain principal and process. The aim of it was accordance the region condition and plan of greening development. Not all land has the first right of ecosystem restoring, under the pressure of woods, food, fuel energy, it should carry through on the base of greening. The guarantee of greening achievement was greening technology, it includes select, ground preparation, monitoning and so on. Yunnan greening zoning was preliminarily discussed in this article, such as greening zoning of Yunnan and greening plan about ever regionalization. We also connectes with the forestry production of Yunnan, according the function of greening, we discuss the regionalization of Yunnan based on the aims of ecology and economy.
