Research On The Examination Of Ecological Reso Jrce Curse And Its Mechanism In Horqin Sandy Land

In the desertification area of North China, it has a poor extent of ecological resource, which is distributed inhomogeneous in spatial scale, which has a strong effect on local ecological safety and social-economic development. When discussing about the agricultural economic growth of desertified area, formal studies mainly focused on the influence of some controllable indice, such as label, capital and land use. However, they ignored the significant role of ecological resource(ER in short). It’ll make a difference to clarify the effect of abundance degree of local ER on the growth of agricultural economy.This article chose Horqin Sandy land as the case zone. Fractional Vegetation Cover index(FVC in short) is obtained through remote sensing interpretation and spectral mixture analysis method. After discussing its changing law in temporal and spatial scale, it is been selected as the representation of ER stock, and considering other indice including agricultural label, fertilization input and cultivated land. After selecting the growth rate of grain yield, this article built the examination model of ecological curse. ARDL cointegration examination is fulfilled to get rid of the distraction of time series. The relationship of abundance extent on agricultural economic growth is analyzed in temporal and spatial scale.(1) The abundance extent of ER had an obvious feature in temporal and spatial scale. The direct behavior is that FVC in the east Horqin district was larger than that of middle and west. Temporally, the ER condition in the east became much better than west under the function of human activity, while it became more barren in the west.(2) ER stock had a strong effect on agricultural economic growth. Spatial regression results showed that the difference of ER distribution is the key reason leading to the different speed of economic growth.18banner’s time-series regression reflected that ER variables in14banners passed the T test.(3)The examination results of resource curse had a significant regional difference. In the east, the utilization of ER had a positive effect on economic growth, meaning that there existed resource curse phenomenon. While in the middle and west, there didn’t exist.(4)ER couldn’t influence agricultural economy directly. It also influenced by other way. It can be determined that ER affected agricultural economy through the variation of agricultural label number and fertilization volume.
