1. In the karst regions, due to the vulnerable ecological environment, large population, backward means of production, low scientific, educational and cultural levels, and the underdeveloped energy, traffic, communication and water conservancy infrastructure construction, the overall economic development level remains very low, far behind the average levels of the non-karst regions and the whole province. The karst regions are usually minority group-inhabited regions, outlying areas and economically underdeveloped regions. In 2010, the gross domestic production of the karst regions hit 271.69 billion yuan, among which the agricultural output value was 48.67 billion yuan, the forestry output value 2.82 billion yuan and the animal husbandry output value 25.65 billion yuan. The farmers’ net income per capita hit 4681 yuan. The economic development in the karst regions is extremely unbalanced due to limitation by natural factors. The southern basin margin regions, the eastern parallel ridge-valley regions and the basin hilly regions are the key rocky desertified regions in Sichuan, where the karst landform is highly developed. These regions have a high population density, sufficient working force, abundant living resources and developed planting industry. However, their vulnerable ecological environment, serious loss of water and soil, barren land, outstanding conflicts between population and resources are detrimental to the sustainable development of the social economy. In the vast southwestern mountain regions, the population density is relatively low and the animal husbandry plays a relatively important role in social economy. However, theses regions have ugly natural conditions, underdeveloped traffic, closed environment, low commodity rate of animal husbandry and extremely underdeveloped economy.
2. As of 2010, the total output value of agriculture in the province-wide desertified regions hit 65.551 billion yuan, among which the animal husbandry took up 33.7 billion yuan and the forestry 4.531 billion yuan. In the desertified land area, the economic and social development, the science, education, culture and health undertakings as well as the public life are relatively backward, the primary industry taking up a high proportion, the regional economy having a fairly limited capacity to support ecological construction.
