Analysis Of The Spatial Coupling Of Natural Resource And Economy In Small Upland Drainage Area

Analysis of The Spatial Coupling of Natural Resource And Economy in Small Upland Drainage Area ——Taking Small Upland Drainage Area of Anji Country of Chekiang Province as Object The spatial coupling of natural resource and economy was studied in small upland drainage area of Anji country. Altitude is the main facts that lead to diversity in this area. According to the different altitude, with the date of TM of SPORT5,field survey and interrelated researching results of inland or overseas, evaluation of the service value of natural resource ,evaluation of the quantity of the service value of natural resource had been transformed into money(TSV) and evaluation of GDP were made every other altitude of 100m. And then, we could calculate the ratio between TSV and the service value of natural resource and the ratio between TSV and GDP. Some conclusions could be made. Bamboo Lin had the highest service value among all kinds Lins of this area; with hypsography became low, the ratio between TSV and the service value of natural resource increased, which could be explained as: with hypsography becoming low, more and more natural resource was exploited; with hypsography becoming high, the ratio between TSV and GDP increased; which could be explained as: with hypsography became high, economy became more depended on locally natural resource, however, with hypsography becoming low, economy became more depended on exotically natural resource; with hypsography becoming low, the service value of natural resource and GDP both increased.
