Arable Land Resources In Heilongjiang Province Safety Warning Analysis

Heilongjiang Province Department of the important national commodity grain productionbase in the region over the years there are a lot of achievements in the protection of arable landresources, due to the impact of natural and anthropogenic factors, arable land resources inHeilongjiang Province is facing the risk of degradation, declining arable land resources. Takinginto account the loss of arable land resources changes in the stock of arable land invisible, in thecontext of high intensity development, how to ensure that the basis of the amount of cultivatedland, as much as possible to improve the quality of arable land to ensure grain output has becomeacademia and land departments the focus. Comprehensive judgment through the analysis of thearable land resources in Heilongjiang Province, safer future trends, approaches, and land useplanning to provide a theoretical basis for the development of farmland protection policiessuitable for the actual situation in Heilongjiang province, as well as the systematic study of thesafety of the area of arable land resources provides a new research ideas and methods.This article summarizes relevant theory on the basis of administrative scope of land inHeilongjiang Province as the study area, and analyzes of the current situation and existingproblems of the area of arable land resources. The study proceeding from the perspective offarmland protection, combined with the actual situation of the arable land resources inHeilongjiang Province to directly affect the quantity of arable land arable land resources security,quality of cultivated land and ecological environment, build warning index system of the safetyof arable land resources in Heilongjiang Province, and gray systems GM (1,1) model and BPartificial neural network technology arable land resources security value in the region2013-2017warning.The analysis results show that: the forecast years2013,2014, arable land resources inHeilongjiang Province in the light alert level; arable land resources in the2015-2017level of thePolice and the warning degree there is an upward trend, no heavy police and giant police stateappears. Ecological environment year after year downward trend in2013-2017, but littlevolatility, land tension between Heilongjiang Province, the existing structure and pattern match;first decline in the amount of cultivated land in2013-2014and then increased significantlyrelated departments to carry out land remediation,2016-2017Number of arable land has reachedsaturation, total expansion of arable land, land reclamation work, to meet the needs of populationgrowth and a downward trend in line with the objective variation; compared to the quality ofcultivated land status is not very optimistic,2013-2017improvement in the quality of cultivated land in2015, followed by a slight downward trend, the volatility of the basic amount ofcultivated land, arable land resources basically meet the overall dynamic balance,2015-2017decline in the quality of cultivated land obvious trend, and the dynasty is still a downward trend.Overall2013-2017arable land resources in Heilongjiang Province security overall downwardtrend, the level of urbanization, soil erosion ratio, grain yields and hazard indices for the alarmcaused by factors affecting the forecast cultivated land resource security. The results of the aboveanalysis, the paper proposes the increase of arable land resources in Heilongjiang Provincesecurity countermeasures should control the population and improve the quality of the population;revitalize the stock of land, increasing the effective cultivation; transformation of low-yieldingfields, raise cropland productivity; governance farmland pollution, protect the ecologicalenvironment; rely on scientific and technological progress, increased investment in agriculture;establish farmland quality dynamic monitoring system aspects.
