Land Use Changes of Mata Lake Using Multi-temporal Satellite Imageries
- Title:
- Land Use Changes of Mata Lake Using Multi-temporal Satellite Imageries
- Keywords:
- land use; TM/ETM+imageries; mata lake; expert system

- 摘要:
- Land use and protection has become a global hot spot.How to use land resources is an important topic for the future socio-economic sustainable development.This paper analyzes the land use changes of Mata lake of Shandong province in China, from 1985’s to 2000’s using multi-temporal remotely sensed data including TM in the 1985s, ETM+in the 2000s and ancillary data such as soil use map, water map etc.The remote sensing imageries were calibrated, registered and geo-referenced, then classified by multi-source information data and remote sensing image interpretation expert system based on knowledge base.Five land use types were extracted from remote sensing imageries, that is, water body, agriculture land, rural settlement, bare land and none-use land.The total precision is 80.7% and Kappa index is 0.825.The analysis result of the remote sensing shows that during the past 15 years, water resource dropped off very promptly from 51.77 km2 to 16.65 km2 and bare land reduced greatly more than 60% in Mata lake region.With the development of the economy and agriculture areas, more and more water body and bare land converted to agriculture land use and rural settlement areas.Since last years, the Mata lake has been affected by natural factor, human activity and increasing population.So its land use pattern greatly changed from 1985 to 2000.The information of land use changes provided scientific supports for land planning and environmental protection.
