Objective:
In the interest of establish planting base of Angelica sinensis on a large scale, enhance economic benefit, and improve decision-making reasons, the eco-climatic applicability of A. sinensis was studied.
Method:
Using integral regression, eco-climatic applicability and the effect of meteorological conditions for the yield of A. sinensis' were analysed by field experimental data.
Result:
Selected > or =0 degrees C accumulated temperature and annual precipitation as leading index, altitude as assistant index, yield and rate of finished products as reference index, the integrated eco-climatic division index and the planting division applicability of A. sinensis was confirmed.
Conclusion:
Accordancing to theory of climate similitude and leading index summarisation, combining with assistant index and reference index, the integrated division index of eco-climate was confirmed. The planting division of co-climate applicability was divided into 5 grades as best suitable, suitable hypo-suitable, just suitable and no suitable regions. At the same time,the way to enhanced utilizing efficiency of eco-climate resources was brought forward.
