The Optimal Depletion Of Phosphate Resources In Yunnan Province To Study

Resource distribution should take the place of border fairly as well as accord with the efficiency principle. The research of optimal consumption is based on the theory of sustainable development, the exhausted speed of resources is identical with its substitutable speed of appearing, namely the appearing time of new substitute is just at the time of the exhaustion of original resources, in order to inimpact contemporary people and subsequent generation normal development of people, implementing sustainable development of resource , environment and society. Meanwhile, the theory of optimal consumption is mutual coordination and unify among optimal exploitation speed, optimal exploitation route and optimal exploitation time. It is independent of people's subjective will, controlled by the objective law of the nature, and restricted and controlled by the development factor and restriction factor in the sustainable development system.The text analyses comprehensively the actuality of phosphoritic resources, exploitation and utilization, management of phosphorite chemical enterprise, production of phosphorite and environmental pollution, economic development, etc. it aims to find optimal exploitation speed, optimal exploitation route and optimal exploitation time of phosphoritic resources by research of rational method of phosphoritic resources' exhausted model, and realize the sustainable development of phosphoritic resources, so as to make coordination and sustainable development of the resource , economy and environment. Additionally, the development of the computer information technology , digitized technology and geographical information system, have offered a technological platform for sustainable development of the phosphorus ore. Meanwhile, it offered the theory , method and means of implementation on this subject, and established the foundation of making the achievement expected. The research has not only improved the research degree of phosphoritic resources sustainable development of Yunnan Province, has offered scientific basis for reasonable exploitation and utilization of phosphoritic resources too.The blind enlargement of phosphoritic resources exploitation and unreasonabledevelopment have caused phosphoritic resources reserves' lasting decline already in Yunnan Province, the rich ore reduced sharply, pollution and seriously environmental effect, its distributed characteristic of space-time and the mechanism of optimal consumption have close relation with unreasonable exploitation of phosphoritic resources. This text proposes much measures ,such as the comprehensive utilization of phosphoritic resources, the concurrent exploitation of rich and poor, the combination of phosphorite and electricity, the full utilization of two markets and two kind resources, strengthen management and control, protecting and rational exploitation, the market adjustment and control, the research of substitute, perfect the phosphoritic resources' sustainable development and environmental protection mechanism further of Yunnan, perfect phosphoritic resources' durative development constantly, set up optimal consumption of phosphoritic resources in Yunnan Province and even development and management model of the whole country, so as to realize lasting development of phosphoritic resources and continuous utilization.
