The legal system governing the preservation of the use of lands and gardens is an important issue in terms of legal, economic and social dimensions, and the necessity of preserving this use as an irrevocable factor and one of the effective elements in sustainable development and a source of judicial security is of particular importance. Before the adoption of the law on the preservation of the use of agricultural lands and gardens in 1374, the parliament passed several laws in order to prevent the division and separation and change of use in agricultural lands and gardens, which were not responsible for the preservation of the use of all lands and gardens, both inside and outside the legal boundaries of cities. On this basis, the change of uses has been increasing until the mentioned law.With the approval of the land use preservation law approved in 1374, the process of changing land use slowed down, but it still did not meet all the legal and social needs of the country, until in November 1385, the amendment to the previous law was approved by the parliament, and despite the inadequacy and shortcomings in the implementation, the land use change process was reduced, but it was definitely not a deterrent.Therefore, in addition to education, revision and elimination of deficiencies in the existing laws, both inside and outside the scope, it seems necessary to approve comprehensive and comprehensive laws in order to reduce the volume of such cases in the judicial authorities and training there.

The implementation process of the Law on Conservation of Use of Agricultural Lands and Gardens is carried out by an administrative authority, and from this point of view, the mentioned process must be in compliance with the criteria and principles of "good management". Accordingly, addressing the conditions and process of law enforcement from the perspective of public law is an undeniable necessity. In this regard, in the present article, by descriptive-analytical method, the compliance of current laws and regulations in the field of implementation of the law on protection of agricultural lands and gardens outside the cities with the criteria of the principles of administrative law has been examined and finally it has been concluded that In the laws in question, The principle of legality is observed more than other principles. The principles of presenting the reasons for administrative decisions, access to the file, observing the reasonable deadline are relatively observed, and the principles of neutrality and independence, legitimate expectation, appropriateness and hearing are generally not applied, and the principle of compensation to citizens In particular, the Court of Administrative Justice is enforceable. Therefore, the mentioned principles have not been paid much attention and observance, and this shows the need to review and amend the existing laws in order to achieve a more desirable and more defensible process.

Protection of agricultural and garden lands is essential; On the other hand, the change of unauthorized uses which has turned into a tragedy, it is possible to prevent the change of unauthorized uses by applying and implementing the rules and regulations governing the preservation of the use of agricultural lands and gardens. Unfortunately, today, land suitable for agriculture, regardless of the achievements they have for mankind, construction operations are carried out in them at a fast pace, which is morally inappropriate. Therefore, the present study was formed with the aim of investigating and morally analyzing the change in the use of agricultural lands and gardens.

The role of agricultural lands to provide food security for today and future generations is very effective, useful, vital and crucial, and protecting agricultural lands is the moral duty of governments. Therefore, the drafting and approval of the Law on the Preservation of Agricultural Lands and Gardens was actually to deal with unauthorized land use changes and the destruction of agricultural lands and their protection and exploitation, because the protection of water, mines and natural resources and agricultural lands is one of the most important issues in environmental ethics. From an ethical point of view, it should be said: the scope of the rule of subordination and the law of preservation of the use of agricultural lands and gardens is related to the exercise of the owner's right of ownership and dominion over his property and the rights of individuals, and although the subject of both categories is the exercise of rights, but the main difference is in this. that the rule of ownership refers to the exercise of ownership of one's own property, and the law of conservation of use refers to the way of exercising ownership rights and protecting the rights of society and its people.

Agricultural land use change caused reducing the employment and food security and increase migration phenomena also. On the other hand, intensification of land use would require huge investments in land improvements to restore fertility of the land. Therefore, conducting investigations on factors affecting land use change seems necessary. This study examines effecting factors on agricultural land use change in the Dezful County. Data for this study was collected through field study by conducting a questionnaire among 205 agricultural exploiters of Dezful County during 2014-2015 crop year applying stratified sampling. To achieve there search’s goal, the logit regression models are applied. The results show that variables like age, family dimension and the space of farm-land have a significant and positive impact while variables like: number family members employed in agriculture, lands distance from the downtown, the land rent, farmers' attitude toward preservation of agricultural land use, considering agriculture as the main occupation and finally quality and fertility of the lands have shown the significant and negative impact on agricultural land use change.
