Variation of cultivated land ecological pressure in Chongqing city based on cultivated land ecological footprint method

The study constructs the exponent of cultivated land ecological pressure., uses the relation of the cultivated land ecological pressure as Pointcut, apply the model of 野cultivated land Ecological Footprints Method冶, consider the factors of cultivated land production revised by Wackernagel, and use IPAT analysis, take the data of the of 2000 and 2010 as an enthesis and making a systematic research in the variation of cultivated land ecological pressure of Chongqing. The results indicated that: (1) Between 2000 and 2010, cultivated land ecological pressure had ameliorated, and exponent of cultivated land ecological pressure had decreased 0.0623. However, cultivated land ecological pressure had been in medium high.(2)Standard of cultivated land ecological pressure positively correlated regional economic development and population. Cultivated land ecological pressure Northeast Chongqing is smaller than one-hour economic circle, and cultivated land ecological pressure southeast economic Chongqing is minimum. (3) Between 2000 and 2010 technology of Chongqing had increased dramatically, the impact force of cultivated land ecotope brought by unit of economic output declined year by year. All in all, the research can provide the ecological security of the area farmland, land consolidation and sustainable development of the area land with scientific evidence and decision support.
