Zoning analysis of Ecosystem Services Value in downtown of Langfang City
Rapid expansion of downtowns would impact some changes of ecosystem in types, acreage and space distribution. The paper calculates the totals and the variation of Ecosystem Services Value with methods of quadrant analysis, and by the table of Chinese ecosystem services value per unit area of different ecosystem types. Results show that in the study area the total area decreases, and changes of Ecosystem Services Value shows biggish difference in every quadrant. Internal transformation of ecosystem types makes their value increase, and the transform amount contributes greatly to Ecosystem Services Value.
