ESTIMATION OF ECOLOGICAL ASSET VALUES IN SHANGRILA BASED ON REMOTELY SENSED DATA

. Ecological assets are an important material base of the national economy and sustainable social development. Shangri-La, China is an important area of forest and farmland that has been returned to forest, but the ecological environment is fragile. It is urgent to start to an ecological asset values estimation study. Choosing remote sensing data, meteorological data, surface observations and statistics as the data sources. The results show: (1) From the perspective of ecological assets, adjusting climate and water conservation contribute the most.(2) In the context of single ecological asset value per unit area, the sequence from highest to lowest is the following, water conservation > adjusting climate > soil and water conservation > production of organic matter > nutrient circulation > cultural entertainment.(3) From the perspective of the type of ecological system, forest and shrub grassland contribute the most. (4) From the value of ecological assets per unit area of each ecosystem type, agricultural land > forest > shrub grassland > waters > wetland > artificial land > permanent snow glacier > unutilized land. It is particularly significant for people to make reasonable decisions when exploiting and utilizing natural resources which can be aided by an ecological asset values estimation study.
