Abstract

Cultivated land is the basis for the survival and development of human society. The selective utilization of human factors and the level of utilization are the decisive factors to promote the external performance of cultivated land. The quality components of cultivated land in different regions have their own characteristics, and the external performance is different. This paper analyzed the China southern city of major grain producing areas of cultivated land within the health influence of constituent elements and characteristics of the relationship between each other, there are dominant factors to find the current utilization level under the influence of the external manifestations of the health of cultivated land, but also conducive to the area of cultivated land ecological function of human selective use, finally get maximum benefit of land use, the best function cultivated land.

Highlights

Cultivated Land is the essential material foundation for the agricultural production and the most basic living condition for the human beings[1].Cultivated health is the ecological system to be able to maintain a dynamic balance
It is not affected by cultivated land fertility, between life and the environment in a certain region of soil pollution, land structure, land use change, land resource constraints, the formation of an energy flow and material circulation dynamic system
In order to provide the basis for rational utilization of healthy cultivated land and the maximum ecological function of healthy cultivated land in the region, the determinant factors affecting the health of cultivated land are found through the analysis of the relationship between the individual characteristics and the components of the components of cultivated land health in the main grain producing areas of southern China

Summary

Introduction

Cultivated Land is the essential material foundation for the agricultural production and the most basic living condition for the human beings[1]. Cultivated health is the ecological system to be able to maintain a dynamic balance. It is not affected by cultivated land fertility, between life and the environment in a certain region of soil pollution, land structure, land use change, land resource constraints, the formation of an energy flow and material circulation dynamic system. Healthy cultivated land has rich fertility, no pollution, land structure is reasonable, land use change is small and land resources are abundant[2],[3],[4]. In order to provide the basis for rational utilization of healthy cultivated land and the maximum ecological function of healthy cultivated land in the region, the determinant factors affecting the health of cultivated land are found through the analysis of the relationship between the individual characteristics and the components of the components of cultivated land health in the main grain producing areas of southern China. In order to ensure and maintain the health of cultivated land, it is necessary to balance the quality of cultivated land, increase the productivity of cultivated land and decrease the soil environment of cultivated land, and not reduce the soil environmental quality of cultivated land on the premise of guaranteeing the quality of cultivated land and the productivity of cultivated land
