Chapter 1: Theories and practices background 
of Thunen model and suburban agriculture rings.
The development of urban areas in both size, quantity and 
population have led to a number of issues, among which is the 
provision of food and foodstuff to urban inhabitants.
Hanoi is the capital, "the heart" of our country. Especially, on 
1/8/2008, the administrative boundary of Hanoi was 
adjusted.
Researching Hanoi suburban agriculture rings based on Von 
Thunen’s agricultural ring theory will contribute to the 
development of Ha Noi towards the effective and sustainable
goals.

INTRODUCTION
2.1 Object
Applying Von Thunen’s theory on the development of agricultural rings 
within the metropolitan influence to research Hanoi suburban agricultural 
rings.
2.2 Mission
„ Overview of Von Thunen’s theory on the suburban agriculture rings and the 
development of agriculture rings within the metropolitan influence
„ Analyzing factors that affect to the generation of Hanoi suburban 
agriculture rings.
„ Applying Thunen’s model to analyze the actual state of Hanoi suburban 
agriculture rings.

agriculture rings till 2020.
2. OBJECT, MISSION AND LIMITATION 
2.3 Limitation
- In content: Applying Thunen’s model to explore the distribution of 
agricultural rings of 8 main agricultural products (rice, maize,
vegetables, flowers, pigs, cattle, poultry and fishery).
- In location: Hanoi Capital after boundary expansion on August 
1st 2008, including 10 districts; Son Tay town and 18 suburb 
districts. Moreover, research boundary is also considered in the
relationship with other nearby areas
- In data source: statistical data published in 2000 and 2007
2. OBJECT, MISSION AND LIMITATION 
RESEARCH STEPS
(I.1) Collect and estimate 
data of agriculture in Hanoi 
suburbs and adjacent areas.
(I.2) Analyze potential 
gravitational values of 
agricultural products.
(II) Analyze the distribution of 
agriculture rings in Hanoi 
suburbs and adjacent areas and 
their relations to city centers.
(III) Evaluating Thunen agricultural structure in Ha Noi

agriculture rings within the metropolitan influence
Content: The pattern of 
the agricultural location, 
shapes into the area of 
concentric ring within the 
metropolitan influence. 
According to Thunen’s 
theory, around a city 
center 5 agricultural 
specialized rings in the 
broad sense may exist and 
be developed .
1.1 Von Thunen’s theory of developing agricultural rings 
around the city centers (1783- 1850)
Relationships between profit of selling agricultural 
products and distance to the market
Argumentations of 
Thunen’s 
agricultural rings
Profit:
P = V – (E + T)
P - Land value to an agricultural product A (unspecified)

1.2 Gravity Model and its application in the construction 
of Thunen agricultural rings structure
„ Gravity model is a potential concept of dynamics which has been 
applied by Stewart for social sciences since 1947
„ Applied Newton’s gravity model to agricultural production, the 
potential value Vo at point O is expressed by following formula:
∑
=
n
i
a
i

D
PG

Vo = 
- Vo represents the potential value at any point O
- Pi represents the agricultural products yields in 
each area i (i = 1, 2... n)
- Di represents the distance from the production 
district O to many other production districts.
- G is the proportional constant; n is the number 
of production districts
- a is the weighted factor which shows the degree 
of influence by distance.

1.3 Method of modelling of Thunen agricultural ring 
based on the Gravity model.
„ In the application of Gravity model 
to research Thunen structure, the 
concept of product - potential is: 
“The summation of forces by which 
the agricultural products are 
drawn to market at some distance 
from the production point 
(district), or that of the influential 
forces on agricultural production 
yields at an area of a certain 
sphere”.

result 3. Defining the structure and distribution of 
agricultural rings in expanded hanoi
Distribution of Agricultural Products with Ha Noi’s citadel 
as the center in 2000 and 2007
Districts in the edge of 
city develop flowers, 
vegetables, poultry, 
fishery. The farthest 
districts from the city 
center develop rice, 
cereal, livestock 
(poultry, cow, pig) 
⇒ The current 
agricultural rings of 
Hanoi quite much 
familiar to Thumen‘s 
structure.
Planning developed agricultural production.
Innovated policies mechanism, consolidated the 
production relations in agriculture. 
Strengthened investment for technical infrastructure.
Application of modern technical progress and technology 
in suburban agricultural production ring. 
Layout and training agriculture labor. 
Established suburban ring agricultural production 
models, development coordinate farm – industrial forms.
result 4. recommending Some solutions to develop 
suburban agricultural rings in Hanoi 
Von Thunen’s agricultural ring theory is an useful tool in 
studying the suburban agriculture rings in Hanoi and the 
agricultural ring in other provinces and cities or in the 
whole country. 
From Thunen’s structure and Gravity model, the study 
has set up a distribution map of potential value for some 
agricultural products and assessed the expanded 
Hanoi’s situation of agricultural production as well as 
the formation and development of the agricultural rings.
Based on the research results, the study has given out 
the orientations and solutions to develop Hanoi suburban 
agriculture rings till 2020.
