(1) China is rich in all kinds of land resources, forming a variety of land types such as cultivated land, woodland and grassland, which is conducive to diversified development and utilization according to local conditions. China's land resources have been utilized, accounting for about 78.4% of the total land area, of which grassland accounts for the largest proportion, which is conducive to the development of animal husbandry, while cultivated land only accounts for 13.5%, accounting for a relatively small proportion.

(2) China's per capita arable land is small, and there are not many arable land resources. The development of industry, transportation and towns occupies a part of cultivated land. In addition, unreasonable utilization leads to serious phenomenon of indiscriminate occupation of cultivated land, which leads to the continuous reduction of cultivated land area. At present, the management and utilization of forest land in China are not reasonable, and the problem of deforestation is still serious. In order to protect, cultivate and make rational use of forest land resources and speed up land greening, we must conscientiously implement the policy of "universal forest protection based on forest management", and implement the forestry policy of "vigorously afforestation, combination of cutting and breeding, and sustainable utilization", and prohibit indiscriminate logging and deforestation. Due to the long-term dependence on the sky to raise livestock, overloading grazing or abandoning grazing to destroy grass for land reclamation, coupled with poor management, 1/3 grassland has been degraded to varying degrees, greatly reducing grassland productivity. Therefore, it is necessary to rotate grazing in different areas, do a good job in disaster prevention and improve grassland productivity.

So the answer is: (1) 78.4; Grassland; Animal husbandry; 13.5; (2) From the aspects of soil and water conservation and farmland protection. , justified can give points.
